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
