The SP724 is a quad array of transient voltage clamping

circuits designed to suppress ESD and other transient

over-voltage events. The SP724 is used to help protect

sensitive digital or analog input circuits on data, signal, or

control lines operating on power supplies up to 20VDC.

• ESD Capability per HBM Standards

- IEC 1000-4-2, Direct Discharge . . . . . . . . 8kV (Level 4)

- IEC 1000-4-2, Air Discharge. . . . . . . . . . 15kV (Level 4)

- MIL STD 3015.7 . . . . . . . . . . . . . . . . . . . . . . . . . . .>8kV

• Input Protection for Applications with Power Supplies Up

to +20V (Single-Ended Voltage), and ±10V (Differential

Voltage)

The SP724 is comprised of bipolar SCR/diode structures to

protect up to four independent lines by clamping transients

of either polarity to the power supply rails. The SP724 offers

very low leakage (1nA Typical) and low input capacitance

(3pF Typical). Additionally, the SP724 is rated to withstand

the IEC 1000-4-2 ESD speciﬁcation for both contact and air

discharge methods to level 4.

• Operating Temperature Range. . . . . . . . . -40 C to 105 C

The SP724 is connected to the sensitive input line and its

associated power supply lines. Clamping action occurs

during the transient pulse, turning on the diode and fast

triggering SCR structures when the voltage on the input line

exceeds one V threshold above the V+ supply (or one

threshold below the V- supply). Therefore, the SP724

operation is unaffected by poor power supply regulation or

voltage ﬂuctuations within its operating range.

NOTES:

1. The design of the SP724 SCR/Diode ESD Protection Arrays is

covered by Harris patent 4567500.

2. The full ESD capability of the SP724 is achieved when wired in a

circuit that includes connection to both the V+ and V- pins. When

handling individual devices, follow proper procedures for

electrostatic discharge.
