Overview

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
  • 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.

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
