Part Manufacturer: Toshiba


Part Description: Low-Voltage Octal Bus Buffer (inverted) with 5-V Tolerant Inputs and Outputs

Part Details:

TC74LCX540F/FW/FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX540F,TC74LCX540FW,TC74LCX540FT,TC74LCX540FK Low-Voltage Octal Bus Buffer (inverted) with 5-V Tolerant Inputs and Outputs Note: xxxFW (JEDEC SOP) is not available in Japan. The TC74LCX540F/FW/FT/FK is a high-performance CMOS octal bus buffer. Designed for use in 3.3-V systems, it achieves TC74LCX540F 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 TC74LCX540F/FW/FT is an inverting 3-state buffer having two active-low output enables. When either 1 OE or 2 OE are high, the terminal outputs are in the high-impedance state. This device is designed to 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 = 6.5 ns (max) (VCC = 3.0 to 3.6 V) TC74LCX540FW · Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V) · Latch-up performance: ±500 mA · Available in JEDEC SOP, JEITA SOP and TSSOP · Power-down protection provided on all inputs and outputs · Pin and function compatible with the 74 series (74AC/VHC/HC/F/ALS/LS etc.) 540 type TC74LCX540FT TC74LCX540FK Weight SOP20-P-300-1.27A : 0.22 g (typ.)
