FK PACKAGE (TOP VIEW) B6 B7 B8 NC VCC A8 A7 D description To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. 4 B5 B4 B3 NC B2 B1 OEAB 5 3 2 1 28 27 26 25 6 24 7 23 8 22 9 21 10 20 11 19 12 13 14 15 16 17 18 A6 A5 A4 NC A3 A2 A1 CLKAB CLKENAB GND NC CLKENBA CLKBA OEBA The ’ABT2952A transceivers consist 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) input provided that the clock-enable (CLKENAB or CLKENBA) input is low. Taking the output-enable (OEAB or OEBA) input low accesses the data on either port. NC – No internal connection The SN54ABT2952A is characterized for operation over the full military temperature range of –55°C to 125°C. The SN74ABT2952A is characterized for operation from –40°C to 85°C.
