8 Bit Binary Counter with Input Register
The TC74HC592A is high speed CMOS 8-BIT REGISTER
COUNTER fabricated with silicon gate C²MOS technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The internal counter counts at positive edge of Counter Clock
(CCK) when Counter Clock Enable ( CCKEN ) is held “L” level. If
Counter clear ( CCLR ) is held “L”, the internal counter is cleared
asynchronously to clock.
Input A to H are loaded to register at positive edge of Register
Clock (RCK), and the register outputs are loaded to Counter
when Counter Load ( CLOAD ) is held “L” level.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• High speed: f_max = 35 MHz (typ.) at V_CC = 5 V
• Low power dissipation: I_CC = 4 μA (max) at Ta = 25°C
• High noise immunity: V_NIH = V_NIL = 28% V_CC (min)
• Output drive capability: 10 LSTTL loads for QA to QH
• Symmetrical output impedance: |I_OH| = I_OL = 4 mA (min)
• Balanced propagation delays: t_pLH ^∼− t_pHL
• Wide operating voltage range: V_CC (opr) = 2 to 6 V
• Pin and function compatible with 74LS592
