| DM74ALS38A Quadruple 2-Input NAND Buffer with Open-Collector Outputs DM74ALS38A Quadruple 2-Input NAND Buffer with Open-Collector Outputs This device contains four independent gates, each of which performs the logic NAND function. The open-collector outputs require external pull-up resistors for proper logical operation. Pull-Up Resistor Equations s Switching specifications at 50 pF s Switching specifications guaranteed over full tempera- ture and VCC range s Advanced oxide-isolated, ion-implanted Schottky TTL process s Functionally and pin for pin compatible with LS TTL counterpart s Improved AC performance over LS38 s Improved line receiving characteristics 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 DM74ALS38AM M14A 14-Lead Small Outline Integrated Circuit SOIC , JEDEC MS-012, Narrow DM74ALS38AN N14A 14-Lead Plastic Dual-In-Line Package PDIP , JEDEC MS-001, Wide Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code. Connection Diagram Function Table Y = AB Inputs H = HIGH Logic Level L = LOW Logic Level Output Y H L 2000 Fairchild Semiconductor Corporation DS006193 DM74ALS38A Absolute Maximum Ratings Note 1 Supply Voltage Input Voltage High Level Output Voltage Operating Free Air Temperature Range Storage Temperature Range Typical N Package M Package 7V 0°C to +70°C −65°C to +150°C 83.0°C/W 114.0°C/W 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. Recommended Operating Conditions Parameter Units Supply Voltage HIGH Level Input Voltage LOW Level Input Voltage HIGH Level Output Voltage LOW Level Output Current Free Air Operating Temperature Electrical Characteristics over recommended operating free air temperature range. All typical values are measured at VCC = 5V, TA = 25°C.
