Product data sheet
1. General description
The 74HC273; 74HCT273 is an octal positive-edge triggered D-type flip-flop. The device
features clock (CP) and master reset (MR) inputs. The outputs Qn will assume the state of their
corresponding Dn inputs that meet the set-up and hold time requirements on the LOW-to-HIGH
clock (CP) transition. A LOW on MR forces the outputs LOW independently of clock and data
inputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface
inputs to voltages in excess of VCC.
2. Features and benefits
Wide supply voltage range from 2.0 V to 6.0 V
CMOS low power dissipation
High noise immunity
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
Complies with JEDEC standards:
JESD8C (2.7 V to 3.6 V)
JESD7A (2.0 V to 6.0 V)
Input levels:
For 74HC273: CMOS level
For 74HCT273: TTL level
Common clock and master reset
Eight positive edge-triggered D-type flip-flops
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Multiple package options
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
