5 / 10 page ![]() Philips Semiconductors Product specification 74F253 Dual 4-input multiplexer (3-State) 1988 Nov 29 5 DC ELECTRICAL CHARACTERISTICS (Over recommended operating free-air temperature range unless otherwise noted.) NO TAG LIMITS SYMBOL PARAMETER TEST CONDITIONSNO TAG MIN TYP NO TAG MAX UNIT VO High level output voltage VCC = MIN, VIL = MAX, ±10%V CC 2.4 V VOH High-level output voltage CC , IL , VIH = MIN, IOH = MAX ±5%V CC 2.7 3.3 V VO Low level output voltage VCC = MIN, VIL = MAX, ±10%V CC 0.35 0.50 V VOL Low-level output voltage CC , IL , VIH = MIN, IOL = MAX ±5%V CC 0.35 0.50 V VIK Input clamp voltage VCC = MIN, II = IIK –0.73 –1.2 V II Input current at maximum input voltage VCC = MAX, VI = 7.0V 100 µA IIH High-level input current VCC = MAX, VI = 2.7V 20 µA IIL Low-level input current VCC = MAX, VI = 0.5V –0.6 mA IOZH Off-state output current High-level voltage applied VCC = MAX, VO = 2.7V 50 µA IOZL Off-state output current Low-level voltage applied VCC = MAX, VO= 0.5V –50 µA IOS Short-circuit output currentNO TAG VCC = MAX –60 –150 mA ICCH OEn=GND, Sn=In=4.5V 10 16 mA ICC Supply current (total) ICCL VCC = MAX OEn=Sn=In=GND 12 23 mA ICCZ OEn=4.5V, Sn=In=GND 14 23 mA NOTES: 1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type. 2. All typical values are at VCC = 5V, Tamb = 25°C. 3. Not more than one output should be shorted at a time. For testing IOS, the use of high-speed test apparatus and/or sample-and-hold techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter tests, IOS tests should be performed last. |
