MC74HCT273A: Octal D Flip-Flop
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.
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 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
- These devices are available in Pb-free package(s). Specifications herein apply to both standard and Pb-free devices. Please see our website at www.onsemi.com for specific Pb-free orderable part numbers, or contact your local ON Semiconductor sales office or representative.
