Programmable Divider/Timer
The TC74HC7292A is a high speed CMOS PROGRAMMABLE
DIVIDER/TIMER fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The TC74HC7292A can divide from 22 to 231.
CK1 and CK2 are clock inputs, either one may be used for clock
gating.
It features an active-low clear input to initialize the state of all
flip-flops.
To facilitate incoming inspection, test points are provided. (TP1,
TP2 and TP3)
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
High speed: fmax = 70 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 to 6 V
Pin and function compatible with 74LS292
