Product specification
Octal transceiver with direction pin; 30
series
termination resistors; 5 V input/output tolerant; 3-state
74LVC2245A
FEATURES
5 V tolerant inputs/outputs for interfacing with 5 V logic
Wide supply voltage range of 1.2 to 3.6 V
CMOS low power consumption
Direct interface with TTL levels
Integrated 30
termination resistors
DESCRIPTION
The 74LVC2245A is a high-performance, low-power,
low-voltage, Si-gate CMOS device, superior to most
advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3 or 5 V devices.
In 3-state operation, outputs can handle 5 V. These
features allow the use of these devices as translators in a
mixed 3.3 V/5 V environment.
The 74LVC2245A is an octal transceiver featuring
non-inverting 3-state bus compatible outputs in both send
and receive directions. The ‘245’ features an output enable
(OE) input for easy cascading and a send/receive (DIR)
input for direction control OE controls the outputs so that
the buses are effectively isolated.
The 74LVC2245A is designed with 30
series termination
resistors in both HIGH and LOW output stages to reduce
line noise.
