DESCRIPTION
The M54/74HC09 is a high speed CMOS QUAD 2-INPUT OPEN DRAIN AND GATE fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption.
The internal circuit is composed of 3 stages including buffer output, which gives high noise immunity and stable output.
All inputs are equipped with protection circuits against static discharge and transient excess voltage.
■ HIGH SPEED
tPD = 6 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 54/74LS09
