The 18-bit PI74ALVCH16823 bus-interface flip-flop is designed for 2.3V to 3.6V VCC operation. It features 3-state outputs designed specifically for driving highly capacitive or relatively lowimpedance loads. This device is particularly suitable for implementing wider buffer registers, I/O ports, bidirectional bus drivers with parity, and working registers. The PI74ALVCH16823 can be used as two 9-bit flip-flops or one 18-bit flip-flop. With the Clock Ena...
