The 74HC244 and 74HCT244 are octal buffer/line drivers featuring 3-state outputs. These devices can function as two 4-bit buffers or one 8-bit buffer, controlled by two output enable signals (1OE and 2OE). A high signal on an output enable pin forces the outputs into a high-impedance OFF-state.
Key electrical characteristics include a wide supply voltage range from 2.0 V to 6.0 V. The input levels differ between the HC and HCT variants, with the 74HCT244 supporting TTL level inputs. These devices offer CMOS low power dissipation and high noise immunity.
They are specified for operation across a broad temperature range, from -40 °C to +125 °C. Available in multiple package options such as SO20, TSSOP20, and DHVQFN20, these buffers are suitable for various board space requirements. The inputs include clamp diodes, allowing the use of current-limiting resistors for interfacing with voltages exceeding VCC.
