MC74HCT595ADTG

Shift Registers Overview

The MC74HCT595ADTG is an 8-bit serial-input/serial or parallel-output shift register with latched 3-state outputs manufactured by onsemi. It operates within a DC supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 30 MHz. The device features asynchronous reset functionality for the shift register and independent clocks for shifting and latching data. It utilizes a TSSOP-16 package and functions across an operating temperature range from -55°C to +125°C.

Shift Registers Feature Summary

• Provides serial-to-parallel conversion capabilities through an 8-bit shift register and an 8-bit D-type latch.
• Features three-state parallel outputs that can be enabled or forced into a high-impedance state via the Output Enable pin.
• Includes an asynchronous active-low reset input that clears only the shift register without affecting the storage latch.

Shift Registers Applications

• Direct interface with SPI serial data ports on CMOS microprocessors and microcontrollers.
• Expansion of I/O lines in digital logic circuits requiring serial data processing.
• Driving displays or indicator arrays where parallel output latching is required.

Shift Registers Procurement Notes

Verify the specific suffix 'DTG' corresponds to the TSSOP-16 package configuration as documented in the ordering information table. Confirm RoHS compliance status and lead-free packaging details against the manufacturer's current documentation before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when TTL-compatible inputs are required alongside standard CMOS performance characteristics. Ensure the application voltage remains strictly between 4.5 V and 5.5 V, as operation outside this range may affect electrical parameters. Consider the 30 MHz maximum clock frequency limit for high-speed timing requirements.

Shift Registers Part Context

This part belongs to the MC74HCT595A series, which represents improvements over previous generations including improved propagation delays and lower quiescent power consumption. The HCT designation indicates compatibility with standard TTL logic levels, distinguishing it from the HC series which requires higher input voltages for high-level recognition.
