74HC253 Dual 4-Bit Multiplexer IC (74253 IC) DIP-16 Package

74HC253 Dual 4-Bit Multiplexer IC (74253 IC) DIP-16 Package The 74HC253 are high-speed Si-gate CMOS device sand are pin compatible with low power Schottky TTL(LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC253 have two identical 4-input multiplexer switch 3-state outputs which select two bits from four sources selected by common data select inputs (S0,S1).When the individual output enable (1OE, 2OE) inputs of the 4-input multiplexers are HIGH, the outputs are forced to the high impedance OFF-state. The “253” is the logic implementation of a 2-pole, 4-position switch, where the position of the switch is determined by the logic levels applied to S0and S1 FEATURES:- Non-inverting data path 3-state outputs for bus interface and multiplex expansion Common select inputs Separate output enable inputs Output capability: bus driver ICC category: MSI Parameter Min Max Unit propagation delay 17 17 ns input capacitance 3.5 3.5 pf ambient temperature -40 +125 °C 3-state output enable time nOE to nY 30 100 ns power dissipation capacitance per multiplexer 55 55 ns output transition time 14 60 ns 3-state output disable time nOE to nY 41 150 ns Package Includes:- 1 x 74HC253 Dual 4-Bit Multiplexer IC (74253 IC) DIP-16 Package
