MAX7393 MAX7394
NAME FUNCTION
1 1 V CC
Positive Supply Voltage Input. Bypass V CC to GND with 0.1µF capacitors placed as close to
the device as possible. Connect V CC to V CC2 .
2 2 GND Ground
3 3 I.C.
Internally Connected. Connect I.C. to GND. Do not connect I.C. to any other input or output.
Do not leave I.C. unconnected.
4 — CLKIN
Clock Input. Connect CLKIN to a returned clock signal source (see the Autoenable (CLKIN,
MAX7393) section).
5 5 CLOCK Clock Output. CLOCK is a rail-to-rail, push-pull output.
6 6 V
CC2
Positive Supply Voltage Input for Output Driver. Bypass V CC2 to GND with a 0.1µF capacitor
placed as close to the device as possible. Connect V CC2 to V CC .
— 4 ENABLE
Enable Input. Drive ENABLE low to place the MAX7394 in shutdown mode. Drive ENABLE
high for normal operation.
— — EP
Exposed Paddle, TDFN Version Only. Connect EP to ground. Do not connect EP to any other
input or output.
