TC74HC153,253AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC153AP, TC74HC153AF TC74HC253AP, TC74HC253AF TC74HC153AP/AF TC74HC253AP/AF Dula 4-Channe Multiplexer Dual 4-Channel Multiplexer with 3-State Output TC74HC153AP, TC74HC253AP The TC74HC153A and TC74HC253A are high speed CMOS DUAL 4-CHANNEL MULTIPLEXERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The TC74HC153A has standard outputs, while the TC74HC253A has 3-state outputs. Input data (1C0~1C2, 2C0~2C3) are selected by the two address inputs, A and B. Separate strobe inputs (1G , 2G ) are provided for each of the two four-line sections. They can be used to inhibit the data outputs. The output of the HC153A is set low, and the HC253A output is set to the high impedance state, when the strobe inputs are low. All inputs are equipped with protection circuits against static discharge or tran...
