ET74HC595

Shift Registers Overview

The ET74HC595 is an 8-bit serial-in, parallel-out shift register with a storage register and three-state outputs. It operates within a voltage range of 2.0 to 6.0 V and supports a maximum frequency of 108 MHz. The device features a transmission delay of 16 ns at 5 V and provides a drive current of +/-7.8 mA for parallel outputs. It is compatible with low-power Schottky TTL (LSTTL) levels and includes asynchronous reset functionality.

Shift Registers Feature Summary

• 8-bit serial input with parallel output capability

• Communication equipment interfaces

Shift Registers Procurement Notes

Verify the specific package variant (SO16, DIP16, SSOP16, or TSSOP16) required for your design, as availability varies by form factor. Confirm that the supplier is an authorized distributor for ETEK Microelectronics to ensure component authenticity. Check for any specific ordering suffixes that may indicate temperature grade or tape-and-reel specifications before finalizing purchase orders.

Shift Registers Selection Notes

Select this component when a CMOS-compatible shift register with latched outputs is needed. Ensure the system voltage falls between 2.0 V and 6.0 V. Consider the 108 MHz maximum frequency if high-speed data shifting is required. Verify that the 16 ns propagation delay meets timing constraints. Choose based on available package types such as SO16 or DIP16 depending on PCB layout requirements.

Shift Registers Part Context

ETEK Microelectronics is a Chinese fabless semiconductor company specializing in power management, signal chain, and driver ICs. The ET74HC595 belongs to their standard logic product line, designed to replace industry-standard 74HC595 devices. It targets markets requiring cost-effective, reliable digital logic components for mass-produced consumer and industrial goods.

Shift Registers Replacement Considerations

Compatible substitutes include the NXP 74HC595, ON Semiconductor 74HC595, and Texas Instruments SN74HC595. These parts share identical pinouts and logical functions. Verify that the alternative manufacturer's datasheet confirms the same 2.0-6.0 V operating range and three-state output characteristics before integration.
