TC74LCX257F

TC74LCX257F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX257F, TC74LCX257FK Low-Voltage Quad 2-Channel Multiplexer (3-state) with 5-V Tolerant Inputs and Outputs The TC74LCX257 is a high-performance CMOS multiplexer. 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 inputs. It is composed of four independent 2-channel multiplexers with common select and OE . If OE is set low, the outputs are held in a high-impedance state. When SELECT is set low, “A” data inputs are enabled. Conversely, when SELECT is high, “B” data inputs are enabled. All inputs are equipped with protection circuits against static discharge. Features Low-voltage operation: VCC = 2.0 to 3.6 V High-speed operation: tpd = 6.0 ns (max) (VCC = 3.0 to 3.6 V) Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V) Latch-up performance: −500 mA Available in JEITA SOP, VSSOP(US) Power-down protection provided on all inputs and outputs Pin and function compatible with the 74 series (74AC/VHC/HC/F/ALS/LS etc.) 257 type TC74LCX257F TC74LCX257FK Weight SOP16-P-300-1.27A VSSOP16-P-0030-0.50 : 0.18 g (typ.) : 0.02 g (typ.) © 2018 1 Toshiba Electronic Devices & Storage Corporation Start of commercial production 1995-02 2018-08-02 Pin Assignment (top view) SELECT 1 1A 2 1B 3 1Y 4 2A 5 2...
