XBLW 74HC/HCT240 Octal Buffers and Line Drivers With 3-State Outputs General Description The 74HC/HCT240 is an 8-bit inverting 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 (1O� and 2O�), each controlling four of the 3-state outputs. A HIGH on nO� 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  Input levels: For 74HC240: CMOS level For 74HCT240: TTL level  Inverting 3-state outputs  Specified from -40℃ to +105℃  Packaging information: DIP20/SOP20/TSSOP20 ORDERING INFORMATION DEVICE Package Type MARKING Packing Packing QTY SN74HC240N SN74HC240DTR SN74HCT240DTR SN74HCT240TDTR DIP-20 SOP-20 SOP-20 TSSOP-20 74HC240N 74HC240 74HCT240 74HCT240 Tube Tape Tape Tape 720/Box 2000/Reel 2000/Reel 2000/Reel XBLW version 1.0 文档仅供参考,实际应用测试为准 www.xinboleic.com       技术支持热线:4009682003 第 1 页 共 17 页 XBLW 74HC/HCT240 Octal Buffers and Line Drivers With 3-State Outputs Block Diagram And Pin Description Block Diagram Figure 1.
