DESCRIPTION

The M54/74HC51 is a high speed CMOS DUAL 2 WIDE-2 INPUT AND/OR INVERT GATE fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. It contains a 2-WIDE 2-INPUT AND-OR-INVERT GATE and a 2-WIDE 3-INPUT AND-OR-INVERT GATE.

■ HIGH SPEED tPD = 10 ns (TYP.) AT VCC = 5 V

■ LOW POWER DISSIPATION ICC = 1 µA (MAX.) AT TA = 25 °C

■ HIGH NOISE IMMUNITY VNIH = VNIL = 28 VCC (MIN.)

■ OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS

■ SYMMETRICAL OUTPUT IMPEDANCE |IOH| = IOL = 4 mA (MIN.)

■ BALANCED PROPAGATION DELAYS tPLH = tPHL

■ WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V

■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS51
