Description
Low Voltage Octal Bus Buffer With 5 V Tolerant Inputs And Outputs
Manufacturer
TOSHIBA Semiconductor CORPORATION
Datasheet
Low Voltage Octal Bus Buffer with 5 V Tolerant Inputs and Outputs
The TC74LCXZA240 is a high-performance CMOS octal bus
buffer. Designed for use in 2.5-V systems, it achieves high-speed
operation while maintaining the CMOS low power dissipation.
The device is designed for low-voltage (2.5V) V
but it could be used to interface to 5-V supply environment for
both inputs and outputs.
When Power supply voltage is turned on, turned off or Vcc is
between 0~1.5V, output will be at high impedance.
For operation at (2.5 V) V
The TC74LCXZA240 is an inverting 3-state buffer having two
active-low output enables. This device is designed to be used with
3-state memory address drivers, etc.
All inputs are equipped with protection circuits against static
discharge.
