74AHC273D,118

Overview

The Nexperia 74AHC273D,118 is a D-type edge-triggered flip-flop belonging to the AHC logic series. It integrates eight independent D-type flip-flops with positive-edge triggering and an asynchronous reset within a single package. The device operates on a supply voltage range of 2 V to 5.5 V. It features single-ended inputs and outputs in a non-inverting configuration. The component is housed in a 20-SOIC surface-mount package. At 5 V, it exhibits a propagation delay of 4.2 ns. Output drive capabilities include -8 mA for high level and 8 mA for low level. The operating temperature range spans from -40 °C to +125 °C.

Procurement Notes

Verify the specific ordering code 74AHC273D,118 against official Nexperia documentation to ensure correct package type and electrical specifications. Confirm compliance requirements such as RoHS and REACH status directly from the manufacturer's datasheet or environmental declaration. Cross-reference the 12NC number 935263592118 for accurate identification in procurement systems. Ensure that the requested quantity matches standard packaging options provided by authorized distributors.

Selection Notes

Select this component when designing systems requiring eight-bit parallel data storage with a common clock and reset signal. The AHC series offers a balance of speed and power consumption suitable for general-purpose digital logic. Consider the 20-SOIC package dimensions for PCB layout constraints. Verify that the input voltage levels are compatible with the driving source within the specified 2 V to 5.5 V range. Evaluate thermal management needs given the extended operating temperature range up to 125 °C.

Part Context

This part belongs to the Nexperia 74AHC family of high-speed CMOS logic devices. The 74AHC273 variant specifically provides octal D-type flip-flops. It is designed to replace older 74HC273 equivalents while offering improved switching speeds and lower power dissipation. The device is widely used in microprocessor-based systems and communication interfaces where reliable data latching is required.

Replacement Considerations

Direct substitutes include other manufacturers' 74AHC273 variants in SOIC-20 packages. Verify pinout compatibility and electrical parameters such as propagation delay and output current before substitution.
