4 / 11 page Philips Semiconductors Product data CBT3257 Quad 1-of-2 multiplexer/demultiplexer 2002 Dec 13 4 ABSOLUTE MAXIMUM RATINGS1 SYMBOL PARAMETER CONDITIONS RATING UNIT VCC DC supply voltage -0.5 to +7.0 V VI DC input voltage2 -0.5 to +7.0 V Continuous channel current 128 mA IK Input clamp current VI/O < 0 -50 mA Tstg Storage temperature range -65 to +150 °C NOTES: 1. 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 input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. RECOMMENDED OPERATING CONDITIONS LIMITS SYMBOL PARAMETER MIN MAX UNIT VCC DC supply voltage 4.5 5.5 V VIH High-level input voltage 2.0 — V VIL Low-level Input voltage — 0.8 V Tamb Operating free-air temperature range -40 +85 °C NOTE: 1. All unused control inputs of the device must be held at VCC or GND to ensure proper device operation. DC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL PARAMETER TEST CONDITIONS Tamb = -40 to +85 °C UNIT MIN TYP1 MAX VIK Input clamp voltage VCC = 4.5 V; II = -18 mA — — -1.2 V VP Pass voltage VI = VCC = 5.0 V; I/O = -100 mA 3.4 3.6 3.9 V II Input leakage current VCC = 5.5 V; VI = GND or 5.5 V — — ±1 µA ICC Quiescent supply current VCC = 5.5 V; IO = 0, VI = VCC or GND — — 3 µA ∆ICC Additional supply current per input pin2 VCC = 5.5 V, one input at 3.4 V, other inputs at VCC or GND — — 2.5 mA CI Control pins VI= 3 V or 0 — 3.3 — pF A port VO = 3 V or 0; OE = VCC — 9.9 — pF CIO(OFF) Power-off leakage current B port VO = 3 V or 0; OE = VCC — 6.4 — pF VCC = 4.5 V; VI = 0V; II = 64 mA — 5 7 Ω ron3 On-resistance VCC = 4.5 V; VI = 0V; II = 30 mA — 5 7 Ω on VCC = 4.5 V; VI = 2.4 V; II = 15 mA — 10 15 Ω NOTES: 1. All typical values are at VCC = 5 V, Tamb = 25 °C. 2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND 3. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On-state resistance is determined by the lowest voltage of the two (A or B) terminals. |
