74LV251DB,112

Signal Switches, Multiplexers, Decoders Overview

The 74LV251DB,112 is an 8-input multiplexer with 3-State outputs manufactured by NXP USA Inc. It operates within a supply voltage range of 1.0 V to 3.6 V and accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V. The device features true and complement outputs, both in the high impedance OFF-state when the output enable input is HIGH. It utilizes a 16-pin Plastic SSOP Type II package (SOT338-1) and functions at temperatures from -40°C to +125°C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Optimized for low voltage applications with a wide operating range
• Provides multifunction capability allowing multiplexing from n-lines to one line
• Features true and complement outputs that are 3-State for expansion

Signal Switches, Multiplexers, Decoders Applications

• Multiplexing multiple data lines to a single output channel
• Expanding multiplexer capacity by tying outputs together
• Low-voltage logic interface circuits requiring 3-State control

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm the component status as active or obsolete through official NXP channels before finalizing procurement plans. Ensure compatibility with existing PCB footprints for the 16-pin SSOP variant.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for designs requiring low-voltage operation down to 1.0 V. It is suitable for systems needing TTL level acceptance at higher voltages within the LV series range. Consider the 3-State output capability if bus expansion or tri-state control is necessary for the application architecture.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices. It is pin and function compatible with the 74HC/HCT251, facilitating direct replacement in legacy designs. The device is categorized under MSI (Medium Scale Integration) logic circuits.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74LV251DB,112 is functionally equivalent to the 74HC251 and 74HCT251 regarding pinout and logic operations. Verify voltage level compatibility when substituting into circuits originally designed for HC or HCT families.
