Introduction
The SN74HCT244-Q1 is an octal buffer and line driver with 3-state outputs. This octal buffer and line driver is specifically designed to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The HCT244 device is configured as two 4-bit buffers/drivers with separate output enable (OE) inputs. When OE is low, the device passes non-inverting data from the A inputs to the Y outputs. When OE is high, the outputs are in a high-impedance state. For all available packages, see the Orderable Addendum at the end of the datasheet.
Features
- Meets automotive application requirements
- ESD protection exceeds 1000V (per MIL-STD-883 Method 3015); exceeds 200V (machine model, C = 200pF, R = 0)
- 4.5V to 5.5V operating voltage range
- High-current outputs drive up to 15 LSTTL loads
- Low power consumption, ICC max = 80μA
- tpd typical = 13ns
- ±6mA output drive at 5V
- Low output current, max 1μA
- TTL-compatible inputs
- 3-state outputs for bus driving or buffered memory address registers
