制造商 : Philips Electronics
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.
