74HCT594N,112

Shift Registers Overview

The 74HCT594N,112 is an 8-bit serial-in, parallel-out shift register with an output register, manufactured by NXP USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features separate positive-edge triggered clocks for the shift (SHCP) and storage (STCP) registers, along with independent direct overriding clears (SHR and STR). It provides a serial output (Q7S) for cascading and is pin-compatible with Low-Power Schottky TTL.

Shift Registers Feature Summary

• Provides synchronous serial input and output capabilities with 8-bit parallel data availability.
• Features independent clocks and direct clear functions for both the shift and storage registers.
• Complies with JEDEC standard No. 7A for logic interface compatibility.

Shift Registers Applications

• Serial-to-parallel data conversion
• Remote control holding register

Shift Registers Procurement Notes

Verify the specific ordering suffix '112' against official NXP documentation to confirm package type and tape/reel specifications. Ensure the component matches the DIP16 plastic dual in-line package description found in the datasheet. Confirm temperature range compliance for your specific application environment before procurement.

Shift Registers Selection Notes

Select this component when LSTTL pin compatibility is required alongside CMOS performance characteristics. The HCT variant ensures proper logic level interfacing with TTL systems while maintaining low power consumption. Verify that the operating voltage remains strictly within the 4.5 V to 5.5 V range to ensure correct VIH and VIL thresholds are met.

Shift Registers Part Context

This part belongs to the 74HCT594 family of 8-bit shift registers with output latches. It is designed as a high-speed Si-gate CMOS device intended for applications requiring reliable data shifting and storage. The N,112 designation specifically identifies the DIP16 package variant within the broader product line.

Shift Registers Replacement Considerations

Direct substitutes include other 74HCT594 variants from NXP or compatible manufacturers offering identical pinouts and electrical specifications. Ensure any replacement maintains the same DIP16 package form factor and meets the required temperature and voltage operating ranges defined in the original datasheet.
