The TC74ACT153 is an advanced high speed CMOS DUAL 4-CHANNEL MULTIPLEXERs fabricated with silicon gate and double-layer metal wiring C2MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipations.

This device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are compatible with TTL, NMOS and CMOS output voltage levels. Each of these data (1C0-1C3, 2C0-2C3) is selected by the two address inputs A and B. Separate strobe inputs ( G1 , G2 ) are provided for each of the

two four-line sections. The strobe input can be used to inhibit the data output; the output is fixed in low level unconditionally. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
