74LV595N,112

Shift Registers Overview

The 74LV595N,112 is an 8-stage serial shift register with a storage register and 3-state outputs. It operates on low-voltage Si-gate CMOS technology within a supply voltage range of 1.0 V to 3.6 V. The device accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V. Data shifts on positive SHCP transitions and transfers to the storage register on STCP transitions. It includes an asynchronous master reset (MR) and supports cascading via a serial output (Q7S). The component is specified for ambient temperatures from −40 °C to +125 °C.

Shift Registers Feature Summary

• Low-voltage operation optimized for applications requiring 1.0 V to 3.6 V power supplies
• TTL-compatible input levels when operating at voltages between 2.7 V and 3.6 V
• Integrated asynchronous master reset for immediate clearing of all shift register stages
• High electrostatic discharge protection exceeding 2000 V under Human Body Model testing

Shift Registers Applications

• Serial-to-parallel data conversion systems
• Remote control holding registers
• Cascaded logic expansion in embedded designs

Shift Registers Procurement Notes

Verify the specific package variant required, as the N suffix denotes a DIP16 plastic dual in-line package. Confirm that the −40 °C to +125 °C temperature range aligns with the target environmental conditions. Ensure input signal levels are compatible with the specified TTL thresholds if operating below 3.6 V. Check for any recent product change notices regarding manufacturing site transfers or label updates.

Shift Registers Selection Notes

Select this component when pin and function compatibility with 74HC/HCT595 devices is necessary but lower voltage operation is required. Consider the DIP16 package constraints regarding board space and thermal dissipation limits above 70 °C. Evaluate the need for 3-state outputs versus standard driver capabilities based on bus loading requirements. Verify that the maximum frequency specifications meet the system clock speeds at the intended supply voltage.

Shift Registers Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices manufactured by NXP Semiconductors. It serves as a direct functional replacement for older 74HC and 74HCT variants while offering improved performance at reduced supply voltages. The device is widely utilized in general-purpose digital logic circuits where serial data expansion is needed.

Shift Registers Replacement Considerations

The 74LV595D, 74LV595DB, and 74LV595PW are alternative package versions of the same logical device. Cross-referencing with other manufacturers' 74LV595 equivalents requires verification of pinout and electrical characteristics.
