DESCRIPTION

The M54/74HC620/623 are high speed CMOS OCTAL BUS TRANSCEIVERS fabricated in silicon gate C2MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption.

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

¡ö LOW POWER DISSIPATION ICC = 4 ?A (MAX.) AT TA = 25 ¡ãC

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

¡ö OUTPUT DRIVE CAPABILITY 15 LSTTL LOADS

¡ö SYMMETRICAL OUTPUT IMPEDANCE |IOH| = IOL = 6 mA (MIN.)

¡ö BALANCED PROPAGATION DELAYS tPLH = tPHL

¡ö WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V to 6 V

¡ö PIN AND FUNCTION COMPATIBLE WITH LS620/623
