SN74ALS273DW TI Flip Flop IC | 20-SOIC | D-Type, Non-Inverting, 8-Bit

Product Overview

The SN74ALS273DW is a high-performance octal D-type flip-flop with clear, designed and manufactured by Texas Instruments (TI). It features eight edge-triggered D-type flip-flops with individual D inputs and Q outputs, plus a common clock (CLK) and master clear (CLR). The device is housed in a 20-pin SOIC package (DW), making it suitable for space-constrained applications. It operates from a 4.5V to 5.5V supply voltage and offers typical propagation delays of 10ns, ensuring high-speed data storage and transfer. The SN74ALS273DW is ideal for use in registers, buffers, and data storage applications where low power consumption and high noise immunity are required.
