MC74HCT273A
Octal D Flip-Flop with
Common Clock and Reset
with LSTTL-Compatible
Inputs
http://onsemi.com
High−Performance Silicon−Gate CMOS
The MC74HCT273A may be used as a level converter for
interfacing TTL or NMOS outputs to High−Speed CMOS inputs.
The HCT273A is identical in pinout to the LS273.
This device consists of eight D flip−flops with common Clock and
Reset inputs. Each flip−flop is loaded with a low−to−high transition of
the Clock input. Reset is asynchronous and active low.

SOIC Package†
This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high−impedance circuit. For proper operation, Vin and
Vout should be constrained to the
range GND v (Vin or Vout) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of
these limits are exceeded, device functionality should not be assumed, damage may occur and
reliability may be affected.
