74LVC827A
10-bit buffer/line driver with 5-volt tolerant
inputs/outputs (3-State)
2
1998 Sep 04
853–2117 19969
FEATURES
5-volt tolerant inputs/outputs, for interfacing with 5-volt logic
Supply voltage range of 2.7V to 3.6V
Complies with JEDEC standard no. 8-1A
CMOS low power consumption
Direct interface with TTL levels
High impedance when V
CC
= 0V
DESCRIPTION
The 74LVC827A is a high performance, low-power, low-voltage
Si-gate CMOS device and superior to most advanced CMOS
compatible TTL families.
Inputs can be driven from either 3.3V or 5.0V devices. In 3-state
operation, outputs can handle 5V. This feature allows the use of
these devices as translators in a mixed 3.3V/5V environment.
The 74LVC827A is a10-bit buffer/line driver with 3-State outputs The
3-State outputs are controlled by the output enable inputs OE
1
and
OE
2
.
A HIGH on OE
n
causes the outputs to assume a high impedance
OFF-state.
