Description
General part information
SN74ALVCH16823 Series
This 18-bit bus-interface flip-flop is designed for 1.65-V to 3.6-V VCCoperation.
The SN74ALVCH16823 features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. This device is particularly suitable for implementing wider buffer registers, I/O ports, bidirectional bus drivers with parity, and working registers.
The SN74ALVCH16823 can be used as two 9-bit flip-flops or one 18-bit flip-flop. With the clock-enable (CLKEN) input low, the D-type flip-flops enter data on the low-to-high transitions of the clock. TakingCLKENhigh disables the clock buffer, thus latching the outputs. Taking the clear (CLR) input low causes the Q outputs to go low independently of the clock.
