SN74AHC1G32DCKRE4

Overview

The SN74AHC1G32DCKRE4 is a single 2-input positive-OR gate from the Texas Instruments AHC series. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature range of -40°C to +125°C. The device features low static power consumption with a maximum quiescent current of 1 µA. It provides symmetric output drive currents of 8 mA for both high and low states. The propagation delay is specified at 7.5 ns when driven at 5V with a 50 pF load capacitance. It is housed in a compact SC-70-5 surface-mount package.

Feature Summary

• Implements single-channel 2-input OR logic functionality
• Operates across extended industrial temperature ranges up to 125°C
• Provides robust 8 mA output drive capability

Applications

• Signal routing and selection circuits
• Logic level translation interfaces
• Digital control systems requiring OR operations

Procurement Notes

Verify the suffix RE4 indicates specific reel packaging configuration distinct from standard tape-and-reel variants. Confirm RoHS compliance status matches current regulatory requirements. Ensure the SC-70-5 footprint aligns with PCB layout constraints. Validate that the extended temperature rating meets system environmental specifications before finalizing procurement orders.

Selection Notes

Select this component when a single OR gate is required in minimal space. The AHC series offers speed comparable to older HC families but with lower power dissipation. Verify input voltage levels match the 2V to 5.5V operational window. Consider the SC-70-5 package dimensions against available board real estate compared to larger TSSOP alternatives.

Part Context

This part belongs to the SN74AHC1Gxx family of single-function gates. It shares pinout compatibility with other devices in the same series, such as NAND or AND gates, facilitating design flexibility. The DCK package variant specifically denotes the SC-70-5 form factor used in compact consumer and industrial electronics designs.

Replacement Considerations

SN74AHC1G32DCKR serves as a direct functional equivalent without the specific RE4 manufacturing designation.
