Hex Buffer

High-Voltage Silicon-Gate CMOS

The SL4503B is a hex noninverting buffer with 3-state outputs

having high sink- and source-current capability. Two output ENABLE

controls are provided, one of which controls four buffers and the other

controls the remaining two buffers.

• 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
