1 / 14 page 54ABT646 Octal Transceivers and Registers with TRI-STATE® Outputs General Description The ’ABT646 consists of bus transceiver circuits with TRI-STATE, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes to a high logic level. Control OE and direction pins are provided to control the transceiver function. In the trans- ceiver mode, data present at the high impedance port may be stored in either the A or the B register or in both. The se- lect controls can multiplex stored and real-time (transparent mode) data. The direction control determines which bus will receive data when the enable control OE is Active LOW. In the isolation mode (control OE HIGH), A data may be stored in the B register and/or B data may be stored in the A regis- ter. Features n Independent registers for A and B buses n Multiplexed real-time and stored data n A and B output sink capability of 48 mA, source capability of 24 mA n Guaranteed multiple output switching specifications n Output switching specified for both 50 pF and 250 pF loads n Guaranteed simultaneous switching noise level and dynamic threshold performance n Guaranteed latchup protection n High impedance glitch free bus loading during entire power up and power down cycle n Nondestructive hot insertion capability n Standard Microcircuit Drawing (SMD) 5962-9457701 Ordering Code Military Package Number Package Description 54ABT646J-QML J24A 24-Lead Ceramic Dual-In-Line 54ABT646W-QML W24C 24-Lead Cerpack 54ABT646E-QML E28A 28-Lead Ceramic Leadless Chip Carrier, Type C TRI-STATE® is a registered trademark of National Semiconductor Corporation.
