Description : STROBED Hex Inverter/Buffer

STROBED Hex Inverter/Buffer
High-Voltage Silicon-Gate CMOS

The SL4502B consists of six inverter/buffers with 3-state outputs. A logic “1” on the OUTPUT ENABLE input produces a high impedance state in all six outputs. This feature permits common busing of the outputs, thus simplifying system design. A logic “1” on the DIRECTION input switches all six outputs to logic “0” if the OUTPUT ENABLE input is a logic “0”.

 • Operating Voltage Range: 3.0 to 18 V
 • Maximum input current of 1 μA at 18 V over full package temperature range; 100 nA at 18 V and 25°C
 • Noise margin (over full package temperature range):
    1.0 V min @ 5.0 V supply
    2.0 V min @ 10.0 V supply
    2.5 V min @ 15.0 V supply
