High–Performance Silicon–Gate CMOS

The MC54/74HCT241A is identical in pinout to the LS241. This device may be used as a level converter for interfacing TTL or NMOS outputs to High–Speed CMOS inputs. The HCT241A is an octal noninverting buffer/line driver/line receiver designed to be used with 3–state memory address drivers, clock drivers, and other bus–oriented systems. The device has non–inverted outputs and two output enables. Enable A is active–low and Enable B is active–high.

The HCT241A is similar in function to the HCT244. See also HCT240.

• Output Drive Capability: 15 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 µA

• In Compliance with the Requirements Defined by JEDEC Standard

No. 7A

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 V

out

should be constrained to the

range GND v (Vin or V

out

) v 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.
