74ABT16652 16-Bit Transceivers and Registers with 3-STATE Outputs April 1993 Revised January 1999 74ABT16652 16-Bit Transceivers and Registers with 3-STATE Outputs General Description The ABT16652 consists of sixteen bus transceiver circuits with D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal registers. Each byte has separate control inputs which can be shorted together for full 16-bit operation. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes to HIGH logic level. Output Enable pins (OEAB, OEBA) are provided to control the transceiver function. Features s Independent registers for A and B buses s Multiplexed real-time and stored data s Separate control logic for each byte s A and B output sink capability of 64 mA, source capability of 32 mA s Guaranteed output skew s High impedance glitch free bus loading during entire power up and power down cycle s Nondestructive hot insertion capability Ordering Code: Order Number 74ABT16652CSSC 74ABT16652CMTD Package Number MS56A MTD56 Package Description 56-Lead Shrink Small Outline Package (SSOP), JEDEC MO-118, 0.300” Wide 56-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide Devices also available in Tape and Reel.
