Drive RESET low to clear all latches and registers (all outputs are turned off). RESET overrides all other inputs. If RESET and SET are pulled low at the same time, then RESET takes precedence. 24 24 CS Chip-Select Input. MAX4820: Drive CS low to select the device. When CS is low, data at DIN is clocked into the 8-bit shift register on SCLK’s rising edge. Drive CS from low to high to latch the data to the registers and activate the appropriate relays. MAX4821: Drive CS low to select the device and set level on LVL. Drive CS from low to high to latch the address and level data to the output. 3 5 — — DIN Serial-Data Input 4 6 — — SCLK Serial-Clock Input 5 7 — — DOUT Serial-Data Output. DOUT is the output of the 8-bit shift register. This output can be used to daisy chain multiple MAX4820s. The data at DOUT appears synchronous to SCLK’s falling edge. 6 8 — — N.C. No Connection 7 9 7 9 GND Ground 8 10 8 10 OUT8 Open-Drain Output 8. Connect OUT8 to the low side of a relay coil. This output is pulled to PGND when activated, but otherwise is high impedance. 9 11 9 11 OUT7 Open-Drain Output 7. Connect OUT7 to the low side of a relay coil. This output is pulled to PGND when activated, but otherwise is high impedance. 10, 16 12, 18 10, 16 12, 18 PGND Power Ground. PGND is a return for the output sinks. Connect PGND pins together and to GND. 11 13 11 13 OUT6 Open-Drain Output 6. Connect OUT6 to the low side of a relay coil. This output is pulled to PGND when activated, but otherwise is high impedance. Typical Operating Characteristics (continued) (VCOM = VCC, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) BACK EMF CLAMPING WITH STANDARD 3V RELAY MAX4820 toc11 200 μs/div VCS 5V/div 0 0 OUT_ 1V/div OUT_ TURNS OFF VCC = 3.3V Pin Description |
