General Description
The ABT652 consists of 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. 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
■ Independent registers for A and B buses
■ Multiplexed real-time and stored data
■ A and B output sink capability of 64 mA, source
   capability of 32 mA
■ Guaranteed output skew
■ Guaranteed multiple output switching specifications
■ Output switching specified for both 50 pF and 250 pF loads
■ Guaranteed simultaneous switching noise level and
   dynamic threshold performance
■ Guaranteed latchup protection
■ High impedance glitch free bus loading during entire
   power up and power down cycle
■ Nondestructive hot insertion capability
