MC74HC595AFEL

Shift Registers Overview

The MC74HC595AFEL is an 8-bit serial-input/serial or parallel-output shift register with latched 3-state outputs, manufactured by onsemi. It integrates an 8-bit shift register and an 8-bit D-type latch with independent clock inputs. The device operates within a supply voltage range of 2.0 V to 6.0 V and supports an operating temperature range from -55°C to +125°C. Propagation delays vary between 24 ns and 140 ns depending on voltage and temperature conditions.

Shift Registers Feature Summary

• Features asynchronous reset for the shift register and independent clocks for shifting and latching operations.
• Provides three-state parallel outputs that directly interface with CMOS, NMOS, and TTL loads.
• Includes a serial output for cascading multiple devices in series configurations.

Shift Registers Applications

• Directly interfaces with SPI serial data ports on CMOS microprocessors and microcontrollers.
• Expands I/O capabilities in digital logic circuits requiring serial-to-parallel conversion.
• Used in display drivers and indicator control systems utilizing cascaded shift registers.

Shift Registers Procurement Notes

Verify the specific suffix 'FEL' against official ordering lists as it may denote specialized packaging or automotive qualification not explicitly detailed in standard datasheets. Confirm RoHS compliance and Pb-free status through manufacturer documentation before procurement.

Shift Registers Selection Notes

Select this component when high noise immunity and low input current are required for CMOS applications. Ensure the operating voltage aligns with the 2.0 V to 6.0 V range. Consider the HC series for broader voltage compatibility compared to HCT variants which are limited to 4.5 V to 5.5 V.

Shift Registers Part Context

This part belongs to the MC74HC595A family of high-performance silicon-gate CMOS logic devices. It offers improved propagation delays and lower quiescent power compared to previous generations. The device complies with JEDEC Standard No. 7A and is available in various surface-mount packages including SOIC-16 and TSSOP-16.

Shift Registers Replacement Considerations

Standard replacements include MC74HC595ADG and MC74HC595ADR2G. Verify pinout and electrical characteristics match requirements. Automotive qualified versions with the '-Q' suffix are available if site-specific control changes are needed.
