TC74HCT688AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HCT688AP, TC74HCT688AF 8-Bit Equality Comparator The TC74HCT688A is a high speed CMOS 8-BIT EQUALITY COMPARATOR fabricated with silicon gate C2MOS technology. 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 compatible with TTL, NMOS and CMOS output voltage leveles. The TC74HCT688A compares two 8-bit binary or BCD words applied inputs P0 thru P7, and inputs Q0 thru Q7, and indicates whether or not they are equal. A signal active low enable is provided to facilitate cascading of several packege to compare of words greater than 8 bits.
