The Toshiba TC74AC257F is an advanced high-speed CMOS multiplexer fabricated with silicon gate and double-layer metal wiring C2MOS technology. It achieves high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining low CMOS power dissipation.
This multiplexer is composed of four independent 2-channel multiplexers with common SELECT and ENABLE OUTPUT (OE) signals. The TC74AC257 is a non-inverting multiplexer. If OE is set low, the outputs are held in a high-impedance state. When SELECT is set low, 'A' data inputs are enabled; conversely, when SELECT is high, 'B' data inputs are enabled. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Key electrical characteristics include a typical propagation delay of 3.6 ns at 5V, a maximum quiescent current of 8 μA at 25°C, and a wide operating voltage range of 2V to 5.5V. The device offers symmetrical output impedance and is capable of driving 50 Ω transmission lines.
The TC74AC257F is supplied in a 16-pin SOP (Small Outline) package, designed for surface mounting. It operates within an industrial temperature range of -40°C to 85°C.
The TC74AC257F operates from 2 V to 5.5 V.
Typical propagation delay is 3.6 ns at VCC = 5 V.
The device operates from -40°C to 85°C.
The TC74AC257F is offered in a SOP-16 package.
The TC74AC257F is RoHS3 compliant.
Maximum quiescent current is 8 μA at 25°C.
Each of the four functions has 2 inputs and 1 output.
