DESCRIPTION
The M54/74HC7245 HC7640, HC7643 and HC7645 utilise silicon gate C2MOS technology to achive operating speeds equivalent to LSTTL devices.
■ HIGH SPEED tPD = 12 ns (TYP.) at VCC = 5V
■ LOW POWER DISSIPATION ICC = 4 µA (MAX.) at TA = 25 °C
■ HIGH NOISE IMMUNITY VH = 1.1 (TYP.) at VCC = 5V
■ OUTPUT DRIVE CAPABILITY 15 LSTTL LOADS
■ SYMMETRICAL OUTPUT IMPEDANCE |IOH| = IOL = 6 mA (MIN)
■ BALANCED PROPAGATION DELAYS tPLH = tPHL
■ WIDE OPERATING RANGE VCC (OPR) = 2V to 6V
■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS245/640/643
