7 / 11 page Philips Semiconductors FAST Products Product specification 74F8965/74F8966 9-Bit address/data Futurebus transceiver, ADT December 19, 1990 7 Notes to function table for 74F8966 1. H = High voltage level 2. h = High voltage level one setup time prior to the low–to–high LE transition 3. L = Low voltage level 4. l = Low voltage level one setup time prior to the low–to–high LE transition 5. NC= No change 6. X = Don’t care 7. Z = High impedance ”off’ state 8. – = Input not externally driven 9. ↑ = Low–to–high transition 10. ↓* = High–to–low transition, latch must be preconditioned before IAREQ 11. H**= Goes to level of pullup voltage. 12. B* = Precaution should be taken to insure B inputs do not float. If they do they are equal to low state. ABSOLUTE MAXIMUM RATINGS (Operation beyond the limit set forth in this table may impair the useful life of the device. Unless otherwise noted these limits are over the operating free air temperature range.) SYMBOL PARAMETER RATING UNIT VCC Supply voltage –0.5 to +7.0 V VIN Input voltage OEB0, OEB1, LEA, LE –0.5 to +7.0 V A0 – A8, B0 – B8 –0.5 to +5.5 V IIN Input current –40 to +5 mA VOUT Voltage applied to output in high output state –0.5 to VCC V A0 – A8 48 mA IOUT Current applied to output in low output state IAMC (74F8966 only) 96 mA B0 – B8 200 mA Tamb Operating free air temperature range 0 to +70 °C Tstg Storage temperature range –65 to +150 °C RECOMMENDED OPERATING CONDITIONS LIMITS SYMBOL PARAMETER MIN NOM MAX UNIT VCC Supply voltage 4.5 5.0 5.5 V VIH High–level input voltage Except B0 – B8 2.0 V B0 – B8 1.625 1.55 V VIL Low–level input voltage Except B0 – B8 0.8 V B0 – B8 1.475 V IIk Input clamp current –18 mA IOH High–level output current A0 – A8 –3 mA VOH High–level output voltage IAMC (74F8966 only) 4.5 V A0 – A8 24 mA IOL Low–level output current IAMC (74F8966 only) 48 mA B0 – B8 100 mA Tamb Operating free air temperature range 0 +70 °C |
