DM74ALS1000AN

Revised February 2000 DM74ALS1000A Quadruple 2-Input NAND Buffer General Description Features These devices contain four independent 2-input buffer/drivers, each of which performs the logic NAND function. The DM74ALS1000A is a buffer/driver version of the DM74ALS00A. ■ Switching specifications at 50 pF ■ Switching specifications guaranteed over full temperature and VCC range ■ Advanced oxide-isolated, ion-implanted Schottky TTL process ■ Improved line receiving characteristics Ordering Code: Order Number Package Number DM74ALS1000AM M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow Package Description DM74ALS1000AN 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. −65°C to +150°C Storage Temperature Range Typical θJA N Package 83.0°C/W M Package 114.0°C/W Recommended Operating Conditions Symbol Parameter Min Nom Max Units 4.5 5 5.5 V LOW Level Input Voltage 0.8 V VCC Supply Voltage VIH HIGH Level Input Voltage VIL 2 V IOH HIGH Level Output Current −2.6 mA IOL LOW Level Output Current 24 mA TA Free Air Operating Temperature 70 °C 0 Electrical Characteristics over recommended operating free air temperature range.
