74LV251D,118

Signal Switches, Multiplexers, Decoders Overview

The NXP USA Inc. 74LV251D,118 is an 8-input multiplexer with 3-State outputs housed in a 16-pin Plastic SO package (SOT109-1). It operates within a DC supply voltage range of 1.0 V to 3.6 V and supports an ambient temperature range from -40°C to +125°C. The device features true and complement outputs that enter a high impedance OFF-state when the output enable input is HIGH. Propagation delays vary by voltage; typical values at 3.3 V are 14 ns for inputs to Y and 19 ns for select inputs to Y.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides multifunction capability allowing multiplexing from n-lines to one line
• Features both true and complement outputs that are 3-State for expansion
• Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V

Signal Switches, Multiplexers, Decoders Applications

• Multiplexing multiple data lines to a single output channel
• Universal function generation using binary inputs
• Expanding multiplexer systems via tied 3-State outputs
