SN74LS273DW Description

Short technical summary and product information.

The Texas Instruments SN74LS273DW is an octal D-type flip-flop with a clear input, utilizing TTL circuitry. This monolithic, positive-edge-triggered flip-flop transfers data meeting setup time requirements to the Q outputs on the positive-going edge of the clock pulse. The D input has no effect on the output when the clock is at a high or low level.

 

Key electrical specifications include a maximum clock frequency of 40 MHz, a maximum propagation delay of 27ns at 5V and 15pF, and an operating voltage range of 4.75V to 5.25V. The device operates within a temperature range of 0°C to 70°C (TA).

 

This component is suitable for applications such as buffer/storage registers and shift registers. It comes in a 20-SOIC surface mount package, measuring 7.50mm in width.

 

The SN74LS273DW is part of the LS technology family and offers a non-inverted output type. It is designed for high-speed operation with a typical power dissipation of 10 milliwatts per flip-flop.
