DESCRIPTION
The 74ALVT16260 is a 12-bit to 24-bit multiplexed D-type latch used
in applications where two separate data paths must be multiplexed
onto, or demultiplexed from, a single data path. Typical applications
include multiplexing and/or demultiplexing of address and data
information in microprocessor or bus-interface applications. This
device is alto useful in memory-interleaving applications.
Three 12-bit I/O ports (A1–A12, 1B1–1B12, and 2B1–2B12) are
available for address and/or data transfer. The output enable (OE1B,
OE2B, and OEA) inputs control the bus transceiver functions. The
OE1B and OE2B control signals also allow bank control in the A to
B direction.
Address and/or data information can be stored using the internal
storage latches. The latch enable (LE1B, LE2B, LEA1B, and
LEA2B) inputs are used to control data storage. When the latch
enable input is high, the latch is transparent. When the latch enable
input goes low, the data present at the inputs is latched and remains
latched until the latch enable input is returned high.
To ensure the high-impedance state during power-up or
power-down, OE should be tied to VCC through a pull-up resistor;
the minimum value of the resistor is determined by the current
sinking capability of the driver.
The 74ALVT16260 is available in a 56-pin Shrink Small Outline
Package (SSOP) and 56-pin Thin Shrink Small Outline Package
(TSSOP).

1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.

General description
The 74ALVT16260 is a 12-bit to 24-bit multiplexed D-type latch used in applications where two separate data paths must
be multiplexed onto, or demultiplexed from, a single data path. Typical applications include multiplexing and/or
demultiplexing of address and data information in microprocessor or bus-interface applications. This device is alto useful in
memory-interleaving applications.
Three 12-bit I/O ports (A1-A12, 1B1-1B12, and 2B1-2B12) are available for address and/or data transfer. The output enable
(OE1B, OE2B, and OEA) inputs control the bus transceiver functions. The OE1B and OE2B control signals also allow bank
control in the A to B direction.
Address and/or data information can be stored using the internal storage latches. The latch enable (LE1B, LE2B, LEA1B,
and LEA2B) inputs are used to control data storage. When the latch enable input is high, the latch is transparent. When the
latch enable input goes low, the data present at the inputs is latched and remains latched until the latch enable input is
returned high.
To ensure the high-impedance state during power-up or power-down, OE should be tied to Vcc through a pull-up resistor;
the minimum value of the resistor is determined by the current sinking capability of the driver.
The 74ALVT16260 is available in a 56-pin Shrink Small Outline Package (SSOP) and 56-pin Thin Shrink Small Outline
Package (TSSOP).

Features
ESD protection exceeds 2000V per Mil-Std-883C, Method 3015; exceeds 200V using machine model
Latch-up protection exceeds 500mA per JEDEC Standard JESD-17.
Distributed Vcc and GND pin configuration minimizes high-speed switching noise.
Output capability (-32mA I OH , 64mA I OL ).
Bus hold inputs eliminate the need for external pull-up resistors.
5V I/O compatible
