TC74HCT157AP Overview
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. This device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are patible with TTL, NMOS and CMOS output voltage levels.
