Product Information

Features

Operating Voltage Range of 4.5 V to 5.5 V
High-Current Outputs Drive Up To 15 LSTTL Loads
Low Power Consumption, 80-µA Max I_CC
Typical t_pd = 13 ns
±6-mA Output Drive at 5 V
Low Input Current of 1 µA Max
Inputs Are TTL-Voltage Compatible
3-State Outputs Drive Bus Lines or Buffer Memory Address Registers

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 ’HCT244 devices are organized as two 4-bit buffers/drivers with separate output-enable (OE)\ inputs. When (OE)\ is low, the device passes noninverted data from the A inputs to the Y outputs. When (OE)\ is high, the outputs are in the high-impedance state.
