DM74ALS273 Octal D-Type Edge-Triggered Flip-Flop with Clear

These monolithic, positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic with a direct clear input.

Information at the D inputs meeting the setup requirements is transferred to the Q outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going pulse. When the clock input is at either the HIGH or LOW level, the D input signal has no effect at the output.
s Switching specifications at 50 pF s Switching specifications guaranteed over full tempera-
ture and VCC range s Buffer-type outputs and improved AC offer significant
advantage over DM74LS273. s Advanced oxide-isolated, ion-implanted Schottky TTL
process s Functionally and pin-for-pin compatible with

DM74LS273.

Note 1 The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation.
