General description
The 74HC161 is a synchronous presettable binary counter with an internal look-head carry. Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive going edge of the clock (CP).

FEATUREs and benefits
• Complies with JEDEC standard no. 7A
• CMOS input levels
• Synchronous counting and loading
• 2 count enable inputs for n-bit cascading
• Asynchronous reset
• Positive-edge triggered clock
• ESD protection:
    • HBM JESD22-A114F exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
• Multiple package options
• Specified from -40 °C to +85 °C and -40 °C to +125 °C
