DESCRIPTION
The 74LVC(H)162245A 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
3.3V or 5V devices. In 3-State operation, outputs can handle 5V.
These features allow the use of these devices in a mixed 3.3V/5V
environment.
The 74LVC(H)162245A is a 16-bit transceiver featuring
non-inverting 3-State bus compatible outputs in both send and
receive directions. The 74LVC(H)162245A features two output
enable (nOE) inputs for easy cascading and two send/receive
(nDIR) inputs for direction control. nOE controls the outputs so that
the buses are effectively isolated. The 74LVC(H)162245A is design
with 30
series termination resistors in both HIGH and LOW output
stages to reduce line noise. This device can be used as two 8-bit
transceivers or one 16-bit transceiver.
The 74LVCH162245A bus hold data inputs eliminates the need for
extreme pull up resistors to hold unused inputs.
