General Description

This device incorporates an octal bus transceiver and an octal D-type register configured to enable multiplexed transmission of data from bus to bus or internal register to bus.

This bus transceiver features totem-pole 3-STATE outputs designed specifically for driving highly-capacitive or relatively low-impedance loads. The high-impedance third state and increased high-logic-level drive provide this device 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

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