MC74HC273A
Octal D Flip-Flop with
Common Clock and Reset
HighâPerformance SiliconâGate CMOS
The MC74HC273A is identical in pinout to the LS273. The device
inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LSTTL outputs.
This device consists of eight D flipâflops with common Clock and
Reset inputs. Each flipâflop is loaded with a lowâtoâhigh transition of
the Clock input. Reset is asynchronous and active low.
Features
⢠Output Drive Capability: 10 LSTTL Loads
⢠Outputs Directly Interface to CMOS, NMOS and TTL
⢠Operating Voltage Range: 2.0 to 6.0 V
⢠Low Input Current: 1.0 mA
⢠High Noise Immunity Characteristic of CMOS Devices
⢠In Compliance with the Requirements Defined by JEDEC Standard
No. 7 A
⢠Chip Complexity: 264 FETs or 66 Equivalent Gates
⢠NLV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AECâQ100
Qualified and PPAP Capable
⢠These Devices are PbâFree, Halogen Free and are RoHS Compliant
