DESCRIPTION
The 74LVC2952A is a low-power, low-voltage, Si-gate CMOS device and superior to most advanced CMOS compatible TTL families. The 74LVC2952A is an octal non-inverting registered transceiver. Two 8-bit back to back registers store data flowing in both directions between two bidirectional busses. Data applied to the inputs is entered and stored on the rising edge of the clock (CPnn) provided that the clock enable CEnn) is LOW. The data is then present at the 3-State output buffers, but is only accessible when the output enable input (OEnn) is LOW. Data flow from A in...
