DESCRIPTION
The M74HC221 is an high speed CMOS MONOSTABLE MULTIVIBRATOR fabricated with silicon gate C2MOS technology.

■ HIGH SPEED : tPD = 24 ns (TYP.) at VCC = 6V
■ LOW POWER DISSIPATION: STAND BY STATE : ICC=4µA (MAX.) at TA=25°C ACTIVE STATE : ICC=700µA (MAX.) at VCC = 5V
■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28 % VCC (MIN.)
■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL
■ WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V
■ WIDE OUTPUT PULSE WIDTH RANGE : tWOUT = 150 ns ~ 60 s OVER AT VCC = 4.5 V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 221
