產品詳細資訊
The 74LCX245FT is a high-performance CMOS octal bus transceiver. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5-V supply environment for both inputs and outputs. The direction of data transmission is determined by the level of the DIR input. The enable input (OE) can be used to disable the device so that the busses are effectively isolated. All inputs are equipped with protection circuits against static discharge. Features (Note) Features (Note) Features (Note) Features (Note)
Low-voltage operation: VCC = 1.65 to 3.6 V
High-speed operation: tpd = 6.5 ns (max) (VCC = 3.0 to 3.6 V)
