SN74HCS164PWR

Shift Registers Overview

The SN74HCS164PWR is an 8-bit parallel-out serial shift register from the Texas Instruments HCS series, housed in a TSSOP-14 package. It operates within a supply voltage range of 2 V to 6 V and supports an ambient temperature range of –40°C to +125°C. The device features balanced CMOS push-pull outputs capable of ±7.8 mA drive current at 6 V. Key electrical characteristics include a typical supply current of 100 nA and input leakage current of ±100 nA. Propagation delays vary by clock frequency, with maximum switching frequencies reaching up to 97 MHz at 6 V.

Shift Registers Feature Summary

• Schmitt-trigger inputs provide high noise immunity and tolerance for slow-edged signals
• AND-gated serial inputs (A and B) allow complete control over data entry
• Asynchronous clear (CLR) input resets all registers to low immediately
• Low power consumption with minimal static supply current

Shift Registers Applications

• Output expansion
• LED matrix control
• 7-segment display control
• 8-bit data storage

Shift Registers Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP-14 package variant. Confirm RoHS compliance status through official manufacturer documentation. Ensure design requirements match the recommended operating conditions for voltage and temperature ranges before procurement.

Shift Registers Selection Notes

Select this component when noisy environments require Schmitt-trigger input hysteresis. The AND-gated serial inputs offer unique control logic compared to standard single-input shift registers. Verify that the required output drive current does not exceed the specified limits for the target supply voltage.

Shift Registers Part Context

This device belongs to the SN74HCS family of HCMOS logic components. It provides enhanced performance over standard HC series devices, particularly regarding noise rejection and power efficiency. The HCS series is designed for applications requiring robust signal integrity across wide voltage and temperature ranges.

Shift Registers Replacement Considerations

Check for pin-compatible alternatives within the SN74HCS164 product line, such as different package options like SN74HCS164D or SN74HCS164BQA. Ensure any substitute maintains the same HCS logic family characteristics and package dimensions.
