MC74HCT273A_06 Datasheet, PDF (1/8 Pages) ON Semiconductor – Octal D Flip−Flop with Common Clock and Reset with LSTTL−Compatible Inputs
MC74HCT273A
Octal D Flip−Flop with
Common Clock and Reset
with LSTTL−Compatible
Inputs
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.
• Output Drive Capability: 10 LSTTL Loads
• TTL/NMOS Compatible Input Levels
• Outputs Directly Interface to CMOS, NMOS and TTL
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 μA
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
• Chip Complexity: 284 FETs or 71 Equivalent Gates
w These devices are available in Pb−free package(s). Specifications herein
apply to both standard and Pb−free devices. Please see our website at
