The device is designed to drive inductive loads such as relays, solenoids, dc and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications. All inputs are compatible with TTL-and low-level CMOS logic. Each output (Y) is a complete totem-pole driver with a Darlington transistor sink and a pseudo-Darlington source. Drivers are enabled in pairs with drivers 1 and 2 enabled by 1,2EN and drivers 3 and 4 enabled by 3,4EN. When an enable input is high, the associated drivers are enabled and their outputs become active and in phase with their inputs. When the enable input is low, those drivers are disabled and their outputs are off and in a high-impedance state. With the proper data inputs, each pair of drivers form a full-H (or bridge) reversible drive suitable for solenoid or motor applications. A separate supply voltage (VCC1) is provided for the logic input circuits to minimize device power dissipation. Supply voltage VCC2 is used for the output circuits. The SN754410 is designed for operation from – 40°C to 85°C. Copyright 1995, Texas Instruments Incorporated PRODUCTION DATA information is current as of publication date.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values are with respect to network GND. 2. For operation above 25°C free-air temperature, derate linearly at the rate of 16.6 mW/°C. To avoid exceeding the design maximum virtual junction temperature, these ratings should not be exceeded. Due to variations in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection can be activated at power levels slightly above or below the rated dissipation. recommended operating conditions MIN MAX Output supply voltage, VCC1 4.5 5.5 V Output supply voltage, VCC2 4.5 36 V High-level input voltage, VIH Low-level input voltage, VIL Operating virtual junction temperature, TJ UNIT 2 5.5 V – 0.3‡ 0.8 V – 40 125 °C Operating free-air temperature, TA – 40 85 °C ‡ The algebraic convention, in which the least positive (most negative) limit is designated as minimum, is used in this data sheet for logic voltage levels. • POST OFFICE BOX 655303 DALLAS, TEXAS 75265 POST OFFICE BOX 1443 HOUSTON, TEXAS 77251–1443 • 3 SN754410 QUADRUPLE HALF-H DRIVER SLRS007B – NOVEMBER 1986 – REVISED NOVEMBER 1995 electrical characteristics over recommended ranges of supply voltage and free-air temperature (unless otherwise noted) PARAMETER TEST CONDITIONS VIK Input clamp voltage II = – 12 mA IOH = – 0.5 A VOH High-level output voltage IOH = – 1 A IOH = – 1 A, VOL Low-level output voltage IOL = 0.5 A IOL = 1 A IOL = 1 A, MIN TJ = 25°C TYP† MAX UNIT – 0.9 – 1.5 V VCC2 – 1.5 VCC2 – 2 VCC2 – 1.1 VCC2 – 1.8 VCC2 – 1.4 1 V 1.4 2 TJ = 25°C 1.2 VO OKH High level output clamp voltage High-level IOK = – 0.5 A IOK = 1 A VCC2 + 1.4 VCC2 + 1.9 IOK = 0.5 A IOK = – 1 A – 1.1 VO OKL Low level output clamp voltage Low-level VCC2 + 2 VCC2 + 2.5 –2 – 1.3 – 2.5 IOZ(off) OZ( ff) Off-state high-impedance-state g output current VO = VCC2 VO = 0 IIH IIL High-level input current Low-level input current VI = 5.5 V VI = 0 ICC1 Output supply current IO = 0 ICC2 Output supply current IO = 0 V 1.8 500 – 500 V µA 10 µA – 10 µA All outputs at high level 38 All outputs at low level 70 All outputs at high impedance 25 All outputs at high level 33 All outputs at low level 20 All outputs at high impedance V mA mA 5 † All typical values are at VCC1 = 5 V, VCC2 = 24 V, TA = 25°C. switching characteristics, VCC1 = 5 V, VCC2 = 24 V, CL = 30 pF, TA = 25°C PARAMETER TEST CONDITIONS MIN TYP MAX UNIT td1 td2 Delay time, high-to-low-level output from A input 400 ns Delay time, low-to-high-level output from A input 800 ns tTLH tTHL Transition time, low-to-high-level output 300 ns 300 ns tr tf Rise time, pulse input tw ten1 Pulse duration Enable time to the high level 700 ns ten2 tdis1 Enable time to the low level 400 ns 900 ns tdis2 Disable time from the low level 600 ns 4 See Figure 1 Transition time, high-to-low-level output Fall time, pulse input See Figure 2 Disable time from the high level • POST OFFICE BOX 655303 DALLAS, TEXAS 75265 POST OFFICE BOX 1443 HOUSTON, TEXAS 77251–1443 • SN754410 QUADRUPLE HALF-H DRIVER SLRS007B – NOVEMBER 1986 – REVISED NOVEMBER 1995 PARAMETER MEASUREMENT INFORMATION Input Pulse Generator (see Note A) 5V tf 24 V VCC1 VCC2 3V 90% 90% Input 1.5 V A Circuit Under Test tr Y 1.5 V 10% 10% tw td1 Output EN 0V td2 V 90% OH 90% CL = 30 pF (see Note B) Output GND 3V 10% 10% TEST CIRCUIT VOL tTHL tTLH VOLTAGE WAVEFORMS Figure 1.
