MC74HCT273A
Octal D Flip-Flop with
Common Clock and Reset
with LSTTL-Compatible
Inputs
HighPerformance SiliconGate CMOS
The MC74HCT273A may be used as a level converter for
interfacing TTL or NMOS outputs to HighSpeed CMOS inputs.
The HCT273A is identical in pinout to the LS273.
This device consists of eight D flipflops with common Clock and
Reset inputs. Each flipflop is loaded with a lowtohigh transition of
the Clock input. Reset is asynchronous and active low.
Features
Output Drive Capability: 10 LSTTL Loads
TTL/NMOS Compatible Input Levels
Outputs Directly Interface to CMOS, NMOS and TTL
Operating Voltage Range: 4.5 V to 5.5 V
Low Input Current: 1.0 μA
In Compliance with the Requirements Defined by JEDEC Standard
No. 7 A
Chip Complexity: 284 FETs or 71 Equivalent Gates
These Devices are PbFree and are RoHS Compliant
