2 / 11 page Absolute Maximum Ratings at Ta = 25°C, VSS = 0 V, VDD = ≥ VCC > VSS ≥ VEE No. 2169-2/11 LC7537N, 7537AN, 7537NE Pin Assignments Equivalent Circuit Block Diagram Specifications Note: 1. A1000 pF or larger capacitor should be added on between each individual power supply terminal and VSS. 2. When the microcomputer side control signals rise faster than VDD for the LC7537, a 2 kΩ or higher resistor should be inserted midway on each of the DI, CLK, and CE lines. 3. When mounting the QIP package on the board, do not dip the entire package in solder. Only the LC7537NE may be dipped directly in solder during mounting.
