1997 Aug 11 853-2020 18266
FEATURES
•Wide supply voltage range of 1.2 V to 3.6 V
•Complies with JEDEC standard no. 8-1A
•CMOS low power consumption
•MULTIBYTETM flow-through standard pin-out architecture
•Low inductance multiple VCC and ground pins for minimum noise
and ground bounce
•Direct interface with TTL levels
•Bus hold on all data inputs eliminates the need for external pull-up
resistors to hold unused inputs
•Output drive capability 50Ω transmission lines @ 85°C
DESCRIPTION
The 74ALVCH16540 is a high-performance, low-power, low-voltage,
Si-gate CMOS device, superior to most advanced CMOS
compatible TTL families.
The 74ALVCH16540 is a 16-bit inverting buf fer/line driver with
3-State outputs. The 3-State outputs are controlled by the output
enable inputs 1OEn and 2OEn. A HIGH on nOEn causes the outputs
to assume a high impedance OFF-state.
Active bus hold circuitry is provided to hold unused or floating data
inputs at a valid logic level. This feature eliminates the need for
external pull-up or pull-down resistors. The device can be used as
four 4-bit buffers, two 8-bit buf fers or one 16-bit buffer.

NOTES:
1. CPD is used to determine the dynamic power dissipation (PD in W):
PD = CPD × VCC2 × fi + (CL × VCC2 × fo) where:
fi = input frequency in MHz; CL = output load capacitance in pF;
fo = output frequency in MHz; VCC = supply voltage in V ;
(CL × VCC2 × fo) = sum of outputs.

General description
The 74ALVCH16540 is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced
CMOS compatible TTL families.
The 74ALVCH16540 is a 16-bit inverting buffer/line driver with 3-State outputs. The 3-State outputs are controlled by the
output enable inputs 1OEn and 2OEn. A HIGH on nOEn causes the outputs to assume a high impedance OFF-state.
Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the
need for external pull-up or pull-down resistors. The device can be used as four 4-bit bufferstwo 8-bit buffers or one 16-bit
buffer.
