LV5232VH
Bi-CMOS IC
16ch LED Driver
Overview
http://onsemi.com
The LV5232VH is a semiconductor integrated circuit that incorporates a serial input and serial or parallel output
16-stage shift register that features a CMOS structure based on Bi-CMOS process technology. The LV5232VH also
contains an n-channel CMOS construction high-withstand-voltage, large-current drive 16-stage parallel output driver.
The protection circuit of the output malfunction is built into.

Caution 1) Absolute maximum ratings represent the values which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

Latch input
When the latch input is held low, the LED0 output status is retained.
When a high-level is input, the LED0 outputs change when the status of the shift register changes.
