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 and 5 V environment.
The 74LVC2245A is an octal transceiver featuring
non-inverting 3-state bus compatible outputs in both send
and receive directions.
The 74LVC2245A 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
resistors in both HIGH and LOW output stages to reduce
line noise.
