74AC648 Datasheet Octal Transceiver/register

Manufacturer: Fairchild (now onsemi)

Overview: 74AC648 Octal Transceiver/Register with 3-STATE Outputs November 1988 Revised August 2000 74AC648 Octal Transceiver/Register with 3-STATE.

General Description

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.

Key Features
