DESCRIPTION
The M54/74HC190/191 are high speed CMOS4-BIT SYNCHRONOUS UP/DOWN COUNTERS fabricated in silicon gate C2MOS technology.
■ HIGH SPEED
fMAX = 48 MHz (TYP.) AT VCC = 5 V
■ LOW POWER DISSIPATION
ICC = 4 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 54/74LS190/191
