The TC74VHC 161 and 163 are advanced high speed CMOS
SYNCHRONOUS PRESETTABLE 4 BIT BINARY COUNTERs
fabricated with silicon gate C2MOS technology.
They achieve the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
The CK input is active on the rising edge. Both LOAD and
CLR inputs are active on low logic level.
Presetting of each IC’s is synchronous to the rising edge of CK.
The clear function of the TC74VHC163 is synchronous to CK,
while the TC74VHC161 are cleared asynchronously.
Two enable inputs (ENP and ENT) and CARRY OUTPUT are
provided to enable easy cascading of counters, which facilitates
easy implementation of n-bit counters without using external
gates.
An input protection circuit ensures that 0 to 5.5 V can be
applied to the input pins without regard to the supply voltage.
This device can be used to interface 5 V to 3 V systems and two
supply systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input voltages.
Features
• High speed: fmax = 185 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)
• Power down protection is provided on all inputs.
• Balanced propagation delays: tpLH ∼− tpHL
• Wide operating voltage range: VCC (opr) = 2 to 5.5 V
• Low noise: VOLP = 0.8 V (max)
• Pin and function compatible with 74ALS161/163
