SNx4HC541 Octal Buers and Line Drivers With 3-State Outputs

1 Features

• Wide Operating Voltage Range of 2 V to 6 V

• High-Current 3-State Outputs Drive Bus Lines

Directly or Up to 15 LSTTL Loads

• Low Power Consumption, 80-µA Maximum ICC

• Typical tpd = 10 ns

• ±6-mA Output Drive at 5 V

• Low Input Current of 1 µA Maximum

• Data Flow-Through Pinout (All Inputs on Opposite

Side From Outputs)

2 Applications

3 Description

These octal buers and line drivers feature the

performance of the SNx4HC541 devices and a pinout

with inputs and outputs on opposite sides of the

package. This arrangement greatly facilitates printed

circuit board layout.

The 3-state outputs are controlled by a two-input

NOR gate. If either output-enable (OE1 or OE2) input

is high, all eight outputs are in the high-impedance

state. The SNx4HC541 devices provide true data at

the outputs.
