74ALS651 datasheet



The 74LAS651 and 74ALS652 transceivers/registers consist of bus transceiver circuits with 3-State outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes High. Output enable (OEAB, OEBA) and select (SAB, SBA) pins are provided for bus management. The 74LAS651-1 and 74ALS652-1 will sink 48mA if the VCCis limited to 5.0V ±0.25V.



1. Independent registers for A and B buses
2. Multiplexed real-time and stored data
3. Choice of non-inverting and inverting data paths
4. 3-State outputs
5. The -1 versions sinks 48mA IOL within the ±5% VCC range
