BU4S71
The BU4S71 is an ultra-compact IC with one circuit of the dual-input positive logic OR gate built into an SMP pack-
age.
•Features
1) Low current dissipation.
2) Super-mini mold package designed for surface
mounting.
3) Wide range of operating power supply voltage.
4) Direct drive of 2 L-TTL inputs and 1 LS-TTL input.
•Absolute maximum ratings (Ta = 25°C)

Note 1: These values indicate the range limits of the voltage that can be applied to each pin without
destroying it. Operation is not guaranteed at these values.
Note 2: Reduced by 1.7mW for each increase in Ta of 1°C over 25°C.
