STMicroelectronics M54HCT165
The M54/74HCT165 is a high speed CMOS 8 BIT PISO SHIFT REGISTER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. It achives the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.- Min Voltage : 4.5V

DESCRIPTION
This device contains eight clocked master slave RS flip-flops connected as a shift register, with auxiliary gating to provide over-riding asynchronous parallel entry. Parallel data entrens when the shift/load input is low. The parallel data can change while shift/load is low, provided that the recommended set-up and hold times are observed. For clocked operation, shift/load must be high. The two clock input perform identically; one can be used as a clock inhibit by applying a high signal; to permit this operation clocking is accomplished through a 2 input nor gates. To avoid double clocking, however, the inhibit signal should only go high while the clock is high. Otherwise the rising inhibit signal will cause the same response as rising clock edge.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 HSCMOS systems with TTL and NMOS components. They are also plug in replacements for LSTTL devices giving a reduction of power consumption.
