TC74LCX16240FT

TC74LCX16240FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX16240FT Low-Voltage 16-Bit Bus Buffer (inverted) with 5-V Tolerant Inputs and Outputs The TC74LCX16240FT is a high-performance CMOS 16-bit bus buffer. Designed for use in 2.5-V or 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. The device is designed for low-voltage (2.5-V or 3.3-V ) VCC applications, but it could be used to interface to 5-V supply environment for both inputs and outputs. This device is inverting 3-state buffer having four active-low output enables. It can be used as four 4-bit buffers two 8-bit buffers or one 16-bit buffer. When the OE input is high, the outputs are in a high-impedance state. This device is designed to Weight: 0.25 g (typ.) be used with 3-state memory address drivers, etc. 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 = 4.5 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 Package: TSSOP Power-down protection provided on all inputs and outputs Start of commercial production 2002-03 1 2014-03-01 Pin Assignment (top view) 1OE 1 1Y1 2 1Y2 3 GND 4 1Y3 5 1Y 4 6 VCC 7 2Y1 8 2Y2 9 GND 10 2Y3 11 2Y4 12 3Y1 13 3Y2 14 GND 15 3Y3 16 3Y4 17 VCC 18 4Y1 19 4Y2 20 GND 21 4Y3 22 4Y4 23 4OE 24 48 2OE 47 1A1 46 1A2 45 GND 44 1A3 43 ...
