74ACTQ646 - Quiet Series Octal Transceiver/Register

Download the 74ACTQ646 datasheet PDF. This datasheet also covers the 74ACQ646 variant, as both devices belong to the same quiet series octal transceiver/register family and are provided as variant models within a single manufacturer datasheet.

General Description

The ACQ/ACTQ646 consist 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.

Key Features

  • GTO output control and undershoot corrector in addition to a split ground bus for superior performance. Features s Guaranteed simultaneous switching noise level and dynamic threshold performance s Guaranteed pin-to-pin skew AC performance s Independent registers for A and B busses s Multiplexed real-time and stored data transfers s 300 mil slim dual-in-line package s Outputs source/sink 24 mA s Faster prop delays than the standard AC/ACT646 Ordering Code: Order Number Package Number Package.

74ACQ646 • 74ACTQ646 Quiet Series Octal Transceiver/Register with 3-STATE Outputs January 1990 Revised September 2000 74ACQ646 • 74ACTQ646 Quiet Series Octal Transceiver/Register with 3-STATE Outputs General Description The ACQ/ACTQ646 consist 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 handling functions available are illustrated in Figure 1, Figure 2, Figure 3 and Figure 4.
