74HC244; 74HCT244 Octal buffer/line driver; 3-state Rev. 5 — 26 February 2016 Product data sheet 1. General description 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. 2. Features and benefits  Input levels:  For 74HC244: CMOS level  For 74HCT244: TTL level  Octal bus interface  Non-inverting 3-state outputs  Complies with JEDEC standard no.
