SN74LVC2952A OCTAL BUS TRANSCEIVER AND REGISTER

ORDERING INFORMATION This octal bus transceiver and register is designed for 1.65-V to 3.6-V VCC operation. The SN74LVC2952A consists of two 8-bit back-to-back registers that store data flowing in both directions between two bidirectional buses. Data on the A or B bus is stored in the registers on the low-to-high transition of the clock (CLKAB or CLKBA) inpu.
