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
Chip Complexity: 118 FETs or 29.5 Equivalent Gates
