Tab: 835-12 rev:B3 Number:AiP74HC/HCT244-AX-LJ-A020EN 1、General Description The AiP74HC/HCT244 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. i-c or e Features:  Input levels: For AiP74HC244: CMOS level For AiP74HCT244: TTL level  Octal bus interface  Non-inverting 3-state outputs  Multiple package options  Specified from -40℃ to +85℃  Packaging information: DIP20/SOP20/TSSOP20 Address：Building B4,NO.777,Jianzhu Road,Binhu Distrct,Wuxi City,Jiangsu Province http://www.i-core. cn P.C.：214072 2/ 16 VER：2019-06-A1 Wuxi I-CORE Electronics Co., Ltd.
