description/ordering information
The CD74HCT4514 and CD74HCT4515 are high-speed silicon-gate devices consisting of a 4-bit strobed latch
and a 4-line to 16-line decoder. The selected output is enabled by a low on the enable (E) input. A high on E

description/ordering information
These octal edge-triggered D-type flip-flops
feature 3-state outputs designed specifically for
bus driving. The ’HCT574 devices are particularly
suitable for implementing buffer registers, I/O
ports, bidirectional bus drivers, and working
registers.
The eight flip-flops enter data on the low-to-high
transition of the clock (CLK) input.
