1. General description
The 74ALVC164245 is a high-performance, low-power, low-voltage, Si-gate CMOS
device, superior to most advanced CMOS compatible TTL families.
The 74ALVC164245 is a 16-bit (dual octal) dual supply translating transceiver featuring
non-inverting 3-state bus compatible outputs in both send and receive directions. It is
designed to interface between a 3 V and 5 V bus in a mixed 3 V and 5 V supply
environment.
This device can be used as two 8-bit transceivers or one 16-bit transceiver.
The direction control inputs (1DIR and 2DIR) determine the direction of the data flow.
nDIR (active HIGH) enables data from nA ports to nB ports. nDIR (active LOW) enables
data from nB ports to nA ports. The output enable inputs (1OE and 2OE), when HIGH,
disable both nA and nB ports by placing them in a high-impedance OFF-state. The nB
ports interface with the 5 V bus. The nA ports interface with the 3 V bus.
In suspend mode, when one of the supply voltages is zero, there will be no current flow
from the non-zero supply towards the zero supply. The A-outputs must be set 3-state and
the voltage on the A-bus must be smaller than Vdiode (typical 0.7 V). VCCB ≥ VCCA (except
in suspend mode).
2. Features
■5 V tolerant inputs/outputs for interfacing with 5 V logic
■Wide supply voltage range:
◆3 V port (VCCA): 1.5 V to 3.6 V
◆5 V port (VCCB): 1.5 V to 5.5 V.
■CMOS low power consumption
■Direct interface with TTL levels
■Control inputs voltage range from 2.7 V to 5.5 V
■Inputs accept voltages up to 5.5 V
■High-impedance outputs when VCCA or VCCB = 0 V
■Complies with JEDEC standard JESD8-B/JESD36
■ESD protection:
◆HBM EIA/JESD22-A114-B exceeds 2000 V
◆MM EIA/JESD22-A115-A exceeds 200 V.
■Specified from −40 °C to +85 °C and −40 °C to +125 °C.

3. Quick reference data
[1] CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2× fi× N + Σ(CL× VCC2× fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in Volts;
N = total load switching outputs;
Σ(CL× VCC2× fo) = sum of the outputs.
[2] The condition is VI = GND to VCC.

X = don’t care;
Z = high-impedance OFF-state.
8. Limiting values
[1] 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.
[2] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

[1] All typical values are measured at nominal voltage for VCCB and VCCA and at Tamb =25°C.
[2] CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2× fi× N + Σ(CL× VCC2× fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in Volts;
N = total load switching outputs;
Σ(CL× VCC2× fo) = sum of the outputs.
[3] The condition is VI = GND to VCC.

Short-form specification — The data in a short-form specification is
extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with
the Absolute Maximum Rating System (IEC 60134). Stress above one or
more of the limiting values may cause permanent damage to the device.
These are stress ratings only and operation of the device at these or at any
other conditions above those given in the Characteristics sections of the
specification is not implied. Exposure to limiting values for extended periods
may affect device reliability.
