| DM7414 Hex Inverter with Schmitt Trigger Input August 1986 Revised July 2001 DM7414 Hex Inverter with Schmitt Trigger Input General Description This device contains six independent gates each of which performs the logic INVERT function. Each input has hysteresis which increases the noise immunity and transforms a slowly changing input signal to a fast changing, jitter free output. Ordering Code: Order Number DM7414N Package Number N14A Package Description 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Connection Diagram Function Table Y=A Input A L H H = HIGH Logic Level L = LOW Logic Level Output Y H L (c) 2001 Fairchild Semiconductor Corporation DS006503 www.fairchildsemi.com DM7414 Absolute Maximum Ratings(Note 1) Supply Voltage Input Voltage Operating Free Air Temperature Range Storage Temperature Range 7V 5.5V 0C to +70C Note 1: The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. 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. -65C to +150C Recommended Operating Conditions Symbol VCC VT+ VT- HYS IOH IOL TA Note 2: VCC = 5V Parameter Supply Voltage Positive-Going Input Threshold Voltage (Note 2) Negative-Going Input Threshold Voltage (Note 2) Input Hysteresis (Note 2) High Level Output Current Low Level Output Current Free Air Operating Temperature Min 4.75 1.5 0.6 0.4 Nom 5 1.7 0.9 0.8 Max 5.25 2 1.1 Units V V V V -0.8 16 0 70 mA mA C Electrical Characteristics over recommended operating free air temperature range (unless otherwise noted) Symbol VI VOH VOL IT+ IT- II IIH IIL IOS ICCH ICCL Parameter Input Clamp Voltage HIGH Level Output Voltage LOW Level Output Voltage Input Current at Positive-Going Threshold Input Current at Negative-Going Threshold Input Current @ Max Input Voltage HIGH Level Input Current LOW Level Input Current Short Circuit Output Current Supply Current with Outputs HIGH Supply Current with Outputs LOW Note 3: All typicals are at VCC = 5V, TA = 25C.
