TC74LCXZ244FT/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LCXZ244FT, TC74LCXZ244FK
Low Voltage Octal Bus Buffer with 5 V Tolerant Inputs and Outputs
The TC74LCXZ244 is a high-performance CMOS octal bus
buffer. 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.
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 (3.3 V) VCC, hot board insertion is applicable.
The TC74LCXZ244 is a non-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.
