74HCT253D-Q100,118

The 74HC253-Q100; 74HCT253-Q100 are high-speed Si-gate CMOS devices and are pin compatible with Low-power Schottky TTL (LSTTL). The 74HC253-Q100; 74HCT253-Q100 provides a dual 4-input multiplexer with 3-state outputs which selects 2 bits of data from up to four sources selected by common data select inputs (S0, S1). The two 4-input multiplexer circuits have individual active LOW output enable inputs (1OE\, 2OE\). The 74HC253-Q100 and 74HCT253-Q100 are the logic implementation of a 2-pole, 4-position switch, where the position of the switch is determined by the logic levels applied to S0 and S1. The outputs are forced to a high-impedance OFF-state when nOE\ is HIGH. The logic equations for the outputs are: 1Y = 1OE\ • (1|0 • S1\ • S0\ + 1|1 • S1\ • S0 + 1|2 • S1 • S0\ + 1|3 • S1 • S0) 2Y = 2OE\ • (2|0 • S1\ • S0\ + 2|1 • S1\ • S0 + 2|2 • S1 • S0\ + 2|3 • S1 • S0) This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
