M54HC294 Datasheet PDF - STMicroelectronics

DESCRIPTION
The 54/74HC292/7292 and HC294/7294 are high speed CMOS PROGRAMMABLE DIVIDER/TIMER fabricated with silicon C2MOS technology.
They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.

■ HIGH SPEED
   fMAX = 70 MHz (TYP.) at VCC = 5 V
■ LOW POWER DISSIPATION
   ICC = 4 mA (MAX.) at TA = 25 oC
■ 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
   54/74LS292/294
