SN74LS193NE4 TI Counter IC | 16-PDIP | 4-Bit, Synchronous, Up/Down

Product Overview

The SN74LS193NE4 is a synchronous, 4-bit up/down binary counter from Texas Instruments, housed in a 16-pin PDIP package. It features a clear function to reset the count to zero and a load function to preset the counter to any 4-bit binary value. The device operates with a typical clock frequency of 25 MHz and a supply voltage range of 4.75 V to 5.25 V. Its synchronous operation ensures reliable counting in high-speed digital systems.
