M74HC160 is a CMOS synchronous 4-bit BCD programmable counter
This datasheet from STMicroelectronics covers the M74HC160, a high speed CMOS synchronous BCD decade presettable counter fabricated with silicon gate C2MOS technology. The clock input is active on the rising edge, the LOAD and CLEAR inputs are active LOW, presetting is synchronous and clearing is asynchronous. Two enable inputs (TE and PE) and a CARRY output allow counters to be cascaded into N-bit counters without external gates, and all inputs have protection circuits against static discharge and transient excess voltage.
The document gives the pin connection and IEC logic symbols, pin description, truth table, logic diagram and timing chart, followed by absolute maximum ratings, recommended operating conditions, DC specifications, AC electrical characteristics, capacitive characteristics, test circuit and waveforms, and mechanical data for the DIP, SOP and TSSOP packages. Order codes are listed for tube and tape and reel packing.

It is a high speed CMOS synchronous BCD decade presettable counter made with silicon gate C2MOS technology.
The recommended operating supply voltage range is 2 V to 6 V.
The clock input is active on the rising edge.
Both the LOAD and CLEAR inputs are active LOW; presetting is synchronous on the clock rising edge while the function is cleared asynchronously.
