SN74LV8154PWR TI Dual 16-Bit Counter | 20-TSSOP | 2V to 5.5V, 20MHz

Product Overview

The SN74LV8154PWR from Texas Instruments is a dual 16-bit binary counter with output storage registers and 3-state output drivers. It operates over a wide supply voltage range of 2V to 5.5V, making it suitable for low-voltage applications. The device features two independent 16-bit counters that can be cascaded for 32-bit operation. Each counter has a storage register that captures the count value on a rising edge of the register clock (RCLK), allowing asynchronous readout while counting continues. The 3-state outputs enable bus-oriented applications. The package is 20-TSSOP, ideal for space-constrained designs.
