74AHCT595D,118

Shift Registers Overview

The Nexperia 74AHCT595D,118 is an 8-bit serial-in/serial or parallel-out shift register with output latches and 3-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL compatible inputs. The device includes separate clocks for the shift and storage registers, a serial input (DS), a serial output (Q7S) for cascading, and an asynchronous master reset (MR). It is housed in a 16-lead SO16 plastic small outline package (SOT109-1) and is specified for operation from -40 °C to +125 °C.

Shift Registers Feature Summary

• Features TTL compatible inputs for direct interfacing with standard logic families.
• Includes overvoltage tolerant inputs allowing use as translators in mixed voltage environments.
• Provides balanced propagation delays and high noise immunity with Schmitt-trigger action on all inputs.

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify that the ordering suffix ',118' corresponds to the SO16 (SOT109-1) package variant. Confirm the specific temperature grade (-40 °C to +125 °C) matches the design requirements. Ensure compatibility with the 4.5 V to 5.5 V supply voltage range required for the AHCT logic family.

Shift Registers Selection Notes

Select this component when TTL-compatible inputs are required alongside AHC performance levels. It serves as a suitable replacement for HC series devices where noise immunity and speed are critical. Verify that the 3-state outputs meet the bus driving requirements of the target application.

Shift Registers Part Context

This part belongs to the 74AHC/AHCT logic family, which combines the high-speed performance of AHC technology with the pinout and input compatibility of standard 74-series logic. The 74AHCT595 specifically bridges CMOS and TTL logic domains, facilitating integration in systems utilizing mixed voltage standards.

Shift Registers Replacement Considerations

Direct functional equivalents include the 74HC595D variants, though input levels differ. Other package options within the same family include 74AHCT595PW (TSSOP16).
