54LS273DM

High-speed 8-bit register integrated circuit (IC) containing eight D-type flip-flops with a common clock and an asynchronous master reset - Logic Function: Octal (8-bit) D-type flip-flop with a shared clock pulse (CP) and master reset (MR).
Triggering: Positive-edge-triggered; information at the data inputs is transferred to the outputs on the rising edge of the clock.
Operating Voltage: Typically operates at a nominal 5V (
).
Temperature Range: The "54" series designation indicates it is rated for the full military temperature range of
to
.
Reset Feature: Includes an asynchronous active-low master reset that clears all eight flip-flops simultaneously, regardless of the clock or data states
