SNx4HC241 Octal Buffers and Line Drivers With 3-State Outputs
1 Features
- Wide operating voltage range of 2 V to 6 V
- High-current outputs drive up to 15 LSTTL loads
- Low power consumption, 80-μA max ICC
- Typical tpd =11 ns
- ±6-mA output drive at 5 V
- Low input current of 1 μA max
- 3-state outputs drive bus lines or buffer memory address registers
2 Description
These octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The ’HC241 devices are organized as two 4-bit buffers/drivers with separate output-enable (1OE and 2OE) inputs. When 1OE is low or 2OE is high, the device passes noninverted data from the A inputs to the Y outputs. When 1OE is high or 2OE is low, the outputs for the respective buffers/drivers are in the high-impedance state.
