description

The SN54ACT16651 and 74ACT16651 are 16-bit

bus transceivers that consist of D-type flip-flops

and control circuitry arranged for multiplexed

transmission of data directly from the data bus or

from the internal storage registers. These devices

can be used as two 8-bit transceivers or one 16-bit

transceiver.

Complementary output-enable (OEAB and

OEBA) inputs are provided to control the

transceiver functions. Select-control (SAB and

SBA) inputs are provided to select whether

real-time or stored data is transferred. A low input

level selects real-time data, and a high input level

selects stored data. The circuitry used for select

control eliminates the typical decoding glitch that

occurs in a multiplexer during the transition

between stored and real-time data. Figure 1

illustrates the four fundamental bus-management

functions that can be performed with the

SN54ACT16651 and 74ACT16651.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

UNLESS OTHERWISE NOTED this document contains PRODUCTION

DATA information current as of publication date. Products conform to

specifications per the terms of Texas Instruments standard warranty.

Production processing does not necessarily include testing of all

parameters.
