ABSOLUTE MAXIMUM RATINGS1

NOTES: 1. Stresses beyond those listed under "absolute maximum ratings" 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. 3. The package thermal impedance is calculated in accordance with JESD 51-7.

NOTES: 1. All typical values are at VCC = 5 V, unless otherwise noted. 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 lower of the voltages of the two (A or B) terminals.
AC CHARACTERISTICS
Tamb = -40 to +85 C; CL = 50 pF, unless otherwise noted. SYMBOL tpd ten tdis PARAMETER Propagation delay1 Output enable time to High and Low level Output disable time from High and Low level FROM (INPUT) A or B OE OE TO (OUTPUT) B or A A or B A or B 1.6 1 VCC = 5 V 0.5 V Min Max 0.25 4.5 4.0 ns ns ns UNIT
NOTE: 1. This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical on-state resistance of the switch and a load capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance).
