Features, Applications

HIGH SPEED tPD 17 ns (TYP.) AT VCC 5 V LOW POWER DISSIPATION ICC 4 A (MAX.) 25 C COMPATIBLE WITH TTL OUTPUTS VIH = 2V (MIN.) VIL = 0.8V (MAX) OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS SYMMETRICAL OUTPUT IMPEDANCE |IOH| = IOL 4 mA (MIN.) BALANCED PROPAGATION DELAYS tPLH = tPHL PIN AND FUNCTION COMPATIBLE WITH 54/74LS688

DESCRIPTION The M54/74HCT688 utilizes silicon gate C2MOS technology to achieve operating speeds equivalent to LSTTL devices. Along with the low power dissipation and high noise immunity of standard C2MOS integrated circuit, it possesses the driving capability of 10 LSTTL load. The M54/74HCT688 compares bit for bit two 8-bit words applied on inputs - P7 and inputs - Q7 and indicates whether or not they are equal. A single active low enable is provided to facilitate cascading several packages to enable comparison of words greater than 8 bits. This integrated circuit has input and output characteristics that are fully compatible with 54/74 LSTTL logic families. M54/74HCT devices are 2 designed to directly interface HSC MOS systems with TTL and NMOS components. They are also plug in replacements for LSTTL devices giving a reduction of power consumption. All inputs are equipped with protection circuit against static discharge and transient excess voltage.
