PIN DESCRIPTIONS

The descriptions of the pins are listed in Table 2-1 and Table 2-2.

FIGURE 2-1:

Typical Input.

TABLE 2-1:

MIC5800 PIN FUNCTION TABLE

Pin Number

Pin Name

Description

1

CLEAR

Resets all latches and turns all outputs OFF (open).

2

STROBE

Input strobe pin. Loads output latches when high.

3, 4, 5, 6

Parallel inputs, 1 through 4.

7

GND

Logic and Output Ground pin.

8

COM

Transient suppression diode common cathode pin.

9, 10, 11, 12

Parallel outputs, 4 through 1.

13

VDD

Logic Supply Voltage.

14

/OE

Output Enable. When low, outputs are active. When high, outputs are inactive and

device is reset from a fault condition. An undervoltage condition emulates a high OE

input.
