Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 C. 3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2003 Feb 06 3 Philips Semiconductors Product data Octal transceiver with direction pin (3-State) 74ABT245 RECOMMENDED OPERATING CONDITIONS LIMITS SYMBOL VCC PARAMETER Min DC supply voltage UNIT Max 4.5 5.5 V 0 VCC V VI Input voltage VIH HIGH-level input voltage VIL LOW-level Input voltage 0.8 V IOH HIGH-level output current -32 mA IOL LOW-level output current 64 mA 0 5 ns/V -40 +85 C 2.0 t/v Input transition rise or fall rate Tamb Operating free-air temperature range V DC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL PARAMETER TEST CONDITIONS Tamb = +25 C Min VIK Input clamp voltage VOH High-level output voltage VOL Low-level output voltage II Input leakage g current VCC = 4.5 V; IIK = -18 mA Typ Max -0.9 -1.2 Tamb = -40 C to +85 C Min UNIT Max -1.2 V VCC = 4.5 V; IOH = -3 mA; VI = VIL or VIH 2.5 2.9 2.5 V VCC = 5.0 V; IOH = -3 mA; VI = VIL or VIH 3.0 3.4 3.0 V VCC = 4.5 V; IOH = -32 mA; VI = VIL or VIH 2.0 2.4 VCC = 4.5 V; IOL = 64 mA; VI = VIL or VIH 0.42 Control pins VCC = 5.5 V; VI = GND or 5.5 V 0.01 Data pins VCC = 5.5 V; VI = GND or 5.5 V 5 2.0 0.55 V 0.55 V 1.0 1.0 A 100 100 A Power-off leakage current VCC = 0.0 V; VI or VO 4.5 V 5.0 100 100 A Power-up/down 3-State output current3 VCC = 2.0 V; VO = 0.5 V; VI = GND or VCC; VOE = Don't care 5.0 50 50 A IIH + IOZH 3-State output High current VCC = 5.5 V; VO = 2.7 V; VI = VIL or VIH 5.0 50 50 A IIL + IOZL 3-State output Low current VCC = 5.5 V; VO = 0.5 V; VI = VIL or VIH -5.0 -50 -50 A ICEX Output high leakage current VCC = 5.5 V; VO = 5.5 V; VI = GND or VCC Output current1 VCC = 5.5 V; VO = 2.5 V IOFF IPU/IPD IO ICCH ICCL Quiescent supply current ICCZ ICC Additional supply current per input pin2 50 A -180 mA 250 250 A 24 30 30 mA VCC = 5.5 V; Outputs 3-State; VI = GND or VCC 50 250 250 A Outputs enabled, one input at 3.4 V, other inputs at VCC or GND; VCC = 5.5 V 0.5 1.5 1.5 mA Outputs 3-State, one data input at 3.4 V, other inputs at VCC or GND; VCC = 5.5 V 50 250 250 A Outputs 3-State, one enable input at 3.4 V, other inputs at VCC or GND; VCC = 5.5 V 0.5 1.5 1.5 mA 5.0 50 -100 -180 VCC = 5.5 V; Outputs HIGH; VI = GND or VCC 50 VCC = 5.5 V; Outputs LOW; VI = GND or VCC -40 -40 NOTES: 1.
