SEMICONDUCTOR TECHNICAL DATA
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 A In Compliance with the Requirements Defined by JEDEC Standard No. 7A * Chip Complexity: 284 FETs or 71 Equivalent Gates

This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the range GND (Vin or Vout) VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
