This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Note 2: Typical values are for Ta = +25C and nominal supply voltages. Note 3: This parameter is only sampled and is not 100% tested. Note 4: OE may be delayed up to tacc~tog after the falling edge of CE without impacting tacc. Note 5: The tonz compare level is determined as follows: High to TRI-STATE, the measured Voy; (DC) 0.10V Low to TRI-STATE, the measured Vo_1 (DC) + 0.10V Note 6: TRI-STATE may be attained using OE or CE. Note 7: The power switching characteristics of EPROMs require careful device decoupling. It is recommended that at least a 0.1 .F ceramic capacitor be used on every device between Voc and GND. Note 8: The outputs must be restricted to Vocg + 0.3V to avoid latch-up and device damage. Note 9: 1 TTL Gate: lol = 1.6 MA, lon = ~400 pA. Ci: 100 pF includes fixture capacitance. Note 10: Vpp may be connected to Voc except during programming.

Toe and Tor are characteristics of the device but must be accommodated by the programmer. Note 1: National's standard product warranty applies only to devices Programmed to specifications described herein. Note 2: Vcc must be applied simultaneously or before Vpp and removed simultaneously or after Vpp. The EPROM must not be inserted into or removed from a board with voltage applied to Vpp or Voc. Note 3: The maximum allowable voltage which may be applied to the Vpp pin during programming is 13V. Care must be taken when switching the Vpp supply to Prevent overshoot exceeding this 13V maximum specification. At least a 0.1 HF capacitor is required across Vpp, Voc to GND to suppress spurious voltage transients which may damage the device.
