74AC648

Octal Transceiver/Register with 3-STATE Outputs

General Description

Features

■ Independent registers for A and B buses

■ Multiplexed real-time and stored data transfers

■ 3-STATE outputs

The AC648 consists of registered bus transceiver circuits,

with outputs, D-type flip-flops and control circuitry providing

multiplexed transmission of data directly from the input bus

or from the internal storage registers. Data on the A or B

bus will be loaded into the respective registers on the

LOW-to-HIGH transition of the appropriate clock pin (CPAB

or CPBA). The four fundamental data handling functions

available are illustrated in Figure 1, Figure 2, Figure 3, and

Figure 4.

■ 300 mil slim dual-in-line package

■ Outputs source/sink 24 mA

■ Inverted data to output
