74ABT646 Octal Transceivers and Registers with 3-STATE Outputs April 1992 Revised November 1999 74ABT646 Octal Transceivers and Registers with 3-STATE Outputs General Description Features The ABT646 consists of bus transceiver circuits with 3-Independent registers for A and B buses STATE, D-type flip-flops, and control circuitry arranged forMultiplexed real-time and stored data multiplexed transmission of data directly from the input bus A and B output sink capability of 64 mA, source capabil- or from the internal registers. Data on the A or B bus will be ity of 32 mA clocked into the registers as the appropriate clock pin goes Guaranteed output skew to a high logic level. Control OE and direction pins are pro- Guaranteed multiple output switching specifications vided to control the transceiver function. In the transceiver mode, data present at the high impedance port may beOutput switching specified for both 50 pF and 250 pF stored in either the A or the B register or in both. The select loads controls can multiplex stored and real-time (transparent Guaranteed simultaneous switching noise level and mode) data. The direction control determines which bus dynamic threshold performance will receive data when the enable control OE is Active Guaranteed latchup protection LOW. In the isolation mode (control OE HIGH), A data may High impedance glitch free bus loading during entire be stored in the B register and/or B data may be stored in power up and power down cycle the A register.
