STMicroelectronics M54HCT164
The M54/74HCT164 is a high speed CMOS 8 BIT SIPO SHIFT REGISTER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. The HCT164 is an 8 bit shift register with serial data entry and an output from each of the eight stages.- Min Voltage : 4.5V
- Max Voltage : 5.5V
- Max Operating Temp : 125°C
- Min Operating Temp : -55°C

DESCRIPTION
Data is entered serially through one of two inputs (A or B), either of these inputs can be used as an active high enable for data entry through the other input. An unused input must be high, or both inputs connected together. Each low-to-high transition on the clock input shifts data one place to the right and enters into QA, the logic NAND of the two data inputs (A● B), the data that existed before the rising clock edge. A low level on the clear input overrides all other inputs and clears the register asynchronously, forcing all Q outputs low. All inputs are equipped with protection circuits against static discharge and transient excess voltage. This integrated circuit has input and output characteristics that are fully compatible with 54/74 LSTTL logic families. M54/74HCT devices are designed to directly interface HSC2MOS systems with TTL and NMOS components. They are also plug in replacements for LSTTL devices giving a reduction of power consumption.
