DM74ALS273
Octal D-Type Edge-Triggered Flip-Flop with Clear
General Description
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.
Features
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.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
