The SN74ALS193AN is a synchronous, reversible, 4-bit up/down binary counter manufactured by Texas Instruments. It features synchronous counting operation, where all flip-flops are clocked simultaneously, eliminating output counting spikes common in ripple-clock counters. The counter's direction is determined by the UP or DOWN count input, and it is fully programmable with a parallel asynchronous load feature for modulo-N count lengths.
This device operates over a temperature range of 0°C to 70°C and requires a supply voltage between 4.5V and 5.5V. It supports a count rate of up to 30 MHz and features an asynchronous clear input. The SN74ALS193AN is available in a 16-pin PDIP package and is designed for through-hole mounting.
Key features include look-ahead circuitry for enhanced cascaded counters, fully synchronous count modes, and buffered UP, DOWN, and LOAD inputs to reduce drive requirements. These characteristics make it suitable for various digital logic applications requiring precise counting and control.
