General Description

This 8-bit register features totem-pole 3-STATE outputs designed specifically for driving highly-capacitive or relatively low-impedance loads. The high-impedance state and increased high-logic-level drive provides this register with the capability of being connected directly to and driving the bus lines in a bus-organized system without need for interface or pull-up components. It is particularly attractive for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

Features

■ Switching specifications at 50 pF

■ Switching specifications guaranteed over full

temperature and VCC range

■ Advanced oxide-isolated, ion-implanted Schottky TTL

process

■ Functionally and pin-for-pin compatible with LS TTL

counterpart

■ Improved AC performance over DM74LS374 at

approximately half the power

■ 3-STATE buffer-type outputs drive bus lines directly
