The 74HC244D,653 from Nexperia is an octal buffer/line driver with 3-state outputs. It can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
The device operates over a wide supply voltage range from 2.0V to 6.0V. It has CMOS input levels and non-inverting outputs. Propagation delay is 165 ns maximum at VCC=5V and CL=50pF. Output current capability is 7.8 mA for both high and low states. The device features high noise immunity and low power dissipation. ESD protection exceeds 2000V HBM and 1000V CDM. Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.
It is specified for operating temperatures from -40°C to +125°C, suitable for automotive applications. The device is surface mounted in a 20-pin SOIC package (SOT163-1) with a body width of 7.5 mm and length of 12.8 mm, and gull wing leads with 1.27 mm pitch. The part is supplied in tape and reel packaging (suffix 653).
The 74HC244D,653 is RoHS compliant and REACH unaffected, with MSL Level 1 for unlimited floor life. It is JEDEC compliant per JESD8C and JESD7A standards.
The supply voltage range is 2V to 6V.
