Key Features
- Synchronous Operation: All flip-flops are clocked simultaneously on the positive-going edge of the clock (CP).
- Presettable: The outputs (Q0 to Q3) of the counters may be preset HIGH or LOW.
- Asynchronous Reset: A LOW at the master reset input (MR) sets Q0 to Q3 LOW regardless of the levels at input pins CP, PE, CET, and CEP.
- Look-ahead Carry: Simplifies serial cascading of the counters.
- Schmitt-trigger Action: At all inputs, making the circuit tolerant of slower input rise and fall times.
- Overvoltage Tolerant Inputs: Up to 5.5 V.
- CMOS Low Power Dissipation: Compatible with TTL levels.
- Wide Supply Voltage Range: From 1.2 V to 3.6 V.
- High-speed Count Rate: Up to 150 MHz.
- ESD Protection: HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V, CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V.
