• Qualified for automotive applications
• ESD protection exceeds 1000 V per MIL-STD-883, Method 3015; exceeds 200 V using machine model (C = 200 pF, R = 0)
• 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 ICC
• 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

This octal buffer and line driver is 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 device is 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.
