Description
Low-Voltage Octal Bus Buffer with 3.6 V Tolerant Inputs and Outputs
Manufacturer
TOSHIBA [Toshiba Semiconductor]
Datasheet
Low-Voltage Octal Bus Buffer with 3.6 V Tolerant Inputs and Outputs
buffer. Designed for use in 1.8 V, 2.5 V or 3.3 V systems, it
achieves high speed operation while maintaining the CMOS low
power dissipation.

3.6 V tolerant inputs and outputs.
Output current: I
Latch-up performance: −300 mA
ESD performance: Machine model ≥ ±200 V
Package: VSSOP (US)
Power down protection is provided on all inputs and outputs.
Supports live insertion/withdrawal (*)
*: To ensure the high-impedance state during power up or power down, OE should be tied to V
pullup resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
