Octal 3-STATE Buffer/Line Driver/Line Receiver

General Description

Features

These buffers/line drivers are designed to improve both the

performance and PC board density of 3-STATE buffers/

drivers employed as memory-address drivers, clock driv-

ers, and bus-oriented transmitters/receivers. Featuring

400 mV of hysteresis at each low current PNP data line

input, they provide improved noise rejection and high

fanout outputs and can be used to drive terminated lines

down to 133Ω.

■ 3-STATE outputs drive bus lines directly

■ PNP inputs reduce DC loading on bus lines

■ Hysteresis at data inputs improves noise margins

■ Typical I_OL(sink current)

24 mA

■ Typical I_OH(source current)

−15 mA

■ Typical propagation delay times

Inverting

10.5 ns

12 ns

Noninverting

■ Typical enable/disable time 18 ns

■ Typical power dissipation (enabled)

Inverting

130 mW

135 mW

Noninverting
