Revised July 2001 DM7407 Hex Buffers with High Voltage Open-Collector Outputs General Description Pull-Up Resistor Equations This device contains six independent gates each of which performs a buffer function. The open-collector outputs require external pull-up resistors for proper logical operation. Where: N1 (IOH) = total maximum output high current for all outputs tied to pull-up resistor N2 (IIH) = total maximum input high current for all inputs tied to pull-up resistor N3 (IIL) = total maximum input low current for all inputs tied to pull-up resistor Ordering Code: Order Number Package Number Package Description DM7407M M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow DM7407N N14A 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. 7V Input Voltage 5.5V Output Voltage 30V 0°C to +70°C Operating Free Air Temperature Range Storage Temperature Range −65°C to +150°C Recommended Operating Conditions Symbol Parameter Min Nom Max 4.75 5 5.25 Units VCC Supply Voltage VIH High Level Input Voltage VIL Low Level Input Voltage 0.8 V VOH High Level Output Voltage 30 V IOL Low Level Output Current 40 mA TA Free Air Operating Temperature 70 °C V 2 V 0 Electrical Characteristics over recommended operating free air temperature range (unless otherwise noted) Symbol Parameter Conditions VI Input Clamp Voltage VCC = Min, II = −12 mA ICEX HIGH Level VCC = Min, VO = 30V Output Current VIH = Min LOW Level VCC = Min, IOL = Max Output Voltage VIL = Max VOL Min Typ (Note 2) Max Units −1.5 V 250 µA 0.7 IOL = 16 mA, VCC = Min V 0.4 II Input Current @ Max Input Voltage VCC = Max, VI = 5.5V 1 IIH HIGH Level Input Current VCC = Max, VI = 2.4V 40 µA IIL LOW Level Input Current VCC = Max, VI = 0.4V −1.6 mA ICCH Supply Current with Outputs HIGH VCC = Max 29 41 mA ICCL Supply Current with Outputs LOW VCC = Max 21 30 mA Min Max Units 10 ns 30 ns mA Note 2: All typicals are at VCC = 5V, TA = 25°C.
