Overview: TC74VHC9164FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VHC9164FK 8-Bit Shift Register (Parallel-IN/ Serial-OUT, Serial -IN/ Parallel -OUT) The TC74VHC9164 is an ultra-high-speed 8-Bit Shift Register fabricated using silicon-gate CMOS technology. The TC74VHC9164 combines low power consumption of CMOS with Schottky TTL speeds.
The TC74VHC9164 has parallel data inputs/outputs, a serial input and a serial output. It converts parallel data into serial data or vice versa.
When P/S CONT is Low, Q/D1 to Q/D8 are configured as parallel data outputs. At this time, the SI input is serially loaded on the rising edges of CK and unloaded from the Q/D1 to Q/D8 outputs in parallel. When CLR/LOAD input is Low, all flip-flops are asynchronously reset, irrespective of the CK state.
When P/S CONT is High, Q/D1 to Q/D8 are configured as parallel data inputs. At this time, when CLR/LOAD is Low, Q/D1 to Q/D8 latch data in parallel asynchronously from the CK input. All the inputs have hysteresis between the positive-going and negative-going thresholds. Thus the TC74VHC9164 is capable of squaring up transitions of slowly changing input signals and provides an improved noise immunity. Additionally, all the inputs have a newly developed protection circuit without a diode returned to VCC. This enables the inputs to be tolerant of up to 5.5 volts even when power supply is down. The input power-down protection capability makes the TC74VHC9164 ideal for a wide range of applications, such as interfacing between different voltages, voltage translation from 5 V to 3 V and battery back-up circuits.
