•Complies with JEDEC standard no. 8-1A
•CMOS low power consumption
•MULTIBYTE
TM
flow-through standard pin-out architecture
•Low inductance multiple power and ground pins for minimum
noise and ground bounce
•Direct interface with TTL levels
DESCRIPTION
The 74LVC16241A 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 74LVC16241A is a 16-bit buf fer/line driver with 3-State outputs.
The 3-State outputs are controlled by the output enable inputs nOE
and nOE. Schmitt-trigger action at all inputs makes the circuit highly
tolerant for slower input rise and fall times. The device can be used
as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer.
