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 I_CC
Typical t_pd =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.

(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2) The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
