Octal buffer/line driver; 3-state

The 74HC244; 74HCT244 is an 8-bit buffer/line driver with 3-state outputs. The device 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.

Features:

• Wide supply voltage range from 2.0 V to 6.0 V
• CMOS low power dissipation • High noise immunity
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
• Input levels: • For 74HC244: CMOS level • For 74HCT244: TTL level
• Octal bus interface
• Non-inverting 3-state outputs
• Complies with JEDEC standards: • JESD8C (2.7 V to 3.6 V) • JESD7A (2.0 V to 6.0 V)
