M74HC151TTR

Overview

The M74HC151TTR is an 8-channel multiplexer from the STMicroelectronics M74HC series, housed in a TSSOP-16 package. It operates on a supply voltage range of 2V to 6V with a maximum quiescent current of 4μA at 25°C. Propagation delay (D-W/Y) ranges from 14ns to 38ns depending on voltage and temperature. The device features complementary outputs Y and W, controlled by address inputs A, B, C, and a strobe input.

Feature Summary

• Provides selection of one bit of data from up to eight sources within a single package
• Features symmetrical output impedance for balanced signal transmission
• Includes protection circuits against static discharge and transient excess voltage on all inputs

Applications

• Universal function generator for logic functions of four variables
• Data routing and signal selection in digital systems
• High-speed data selector applications requiring low power dissipation

Procurement Notes

Verify the specific ordering code suffix matches the required package type, as the M74HC151 family includes DIP, SOP, and TSSOP variants. Confirm that the TSSOP-16 configuration aligns with your PCB footprint requirements. Ensure compatibility with the intended operating voltage range between 2V and 6V before finalizing procurement specifications.

Selection Notes

Select this component when an 8-to-1 data selection capability is required alongside high noise immunity and low power consumption. The HC logic series offers speed performance comparable to AC/ACT families but with lower power usage. Verify that the propagation delay characteristics meet the timing constraints of your specific application circuit design.

Part Context

This part belongs to the M74HC151 family of high-speed CMOS multiplexers. It is pin and function compatible with standard 74 series 151 devices, facilitating direct replacement in legacy designs. The technology utilizes silicon gate C2MOS fabrication to achieve high speed and low power dissipation simultaneously.

Replacement Considerations

Check for equivalent parts from other manufacturers offering the same 8-channel multiplexer functionality in a TSSOP-16 package. Ensure that any substitute maintains the 2V to 6V operating voltage range and similar propagation delay specifications.
