54HC164
54HC164 is 8 bit String into and out of the shift register manufactured by FUMAN ELECTRONICS.
DESCRIPTION
These 8-bit shift registers feature
AND-gated serial inputs and an asynchronous clear (CLR) input. The gated serial (A and B) inputs permit plete control over ining data; a low at either input inhibits entry of the new data and resets the first flip-flop to the low level at the next clock (CLK) pulse. A high-level input enables the other input, which then determines the state of the f1irst flip-flop. Data at the serial inputs can be ch2anged while CLK is high or low, provided the minimum setup time requirements are met. Clocking occurs on the low-to-high-level transition of CLK.
The 54HC164 is characterized for operation over the full military temperature range of
- 55℃ to 125℃. The
74HC164 is characterized for operation from -40℃ to 85℃. 1
