TC74VCX257FT CMOS Digital Integrated Circuits Silicon Monolithic TC74VCX257FT 1. Functional Description Low-Voltage Quad 2-Channel Multiplexer with 3.6-V Tolerant Inputs and Outputs 2. General The TC74VCX257FT is a high performance CMOS multiplexer which is guaranteed to operate from 1.2 V to 3.6 V. Designed for use in 1.5 V, 1.8 V, 2.5 V or 3.3 V systems, it achieves high speed operation while maintaining the CMOS low power dissipation. It is also designed with over voltage tolerant inputs and outputs up to 3.6 V. It consists of four 2-input digital multiplexers with common select and output enable inputs. If OE is set high the outputs are held in a high-impedance state. The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs. All inputs are equipped with protection circuits against static discharge. 3. Features (1) Wide operating temperature range: T = -40 to 125 (Note 1) opr (2) Low-voltage operation: V = 1.2 to 3.6 V CC (3) High-speed operation: t = 3.0 ns (max) (V = 3.0 to 3.6 V) pd CC t = 4.0 ns (max) (V = 2.3 to 2.7 V) pd CC t = 8.0 ns (max) (V = 1.65 to 1.95 V) pd CC t = 16.0 ns (max) (V = 1.4 to 1.6 V) pd CC t = 40.0 ns (max) (V = 1.2 V) pd CC (4) Output current: I /I = 24 mA (min) (V = 3.0 V) OH OL CC I /I = 18 mA (min) (V = 2.3 V) OH OL CC I /I = 6 mA (min) (V = 1.65 V) OH OL CC I /I = 2 mA (min) (V = 1.4 V) OH OL CC (5) 3.6 V tolerant function and power-down protection provided on all inputs and outputs.
