The SN74HC161D from Texas Instruments is a versatile 4-bit synchronous binary counter designed for high-speed counting applications. It features internal carry look-ahead for efficient cascading in n-bit designs.
This counter operates synchronously, meaning all flip-flops are clocked simultaneously, eliminating output counting spikes. It supports synchronous presetting to any number between 0 and 15, with an asynchronous clear function. The device operates over a wide voltage range of 2V to 6V and has a typical propagation delay (tpd) of 14 ns.
Key electrical characteristics include a count rate of 36 MHz, a typical output drive of ±4 mA at 5V, and low power consumption with a maximum Icc of 80 µA. The input current is also minimal, at 1 µA maximum. The SN74HC161D is designed to drive up to 10 LSTTL loads.
Packaged in a 16-SOIC (0.154", 3.90mm Width) surface-mount package, this counter is suitable for various digital logic applications requiring precise and synchronous counting.
