11 / 20 page www.ti.com Switching Characteristics Interrupt and Reset Timing Requirements PCA9543A TWO-CHANNEL I2C-BUS SWITCH WITH INTERRUPT LOGIC AND RESET SCPS169 – SEPTEMBER 2007 over recommended operating free-air temperature range, CL ≤ 100 pF (unless otherwise noted) (see Figure 13) FROM TO PARAMETER MIN MAX UNIT (INPUT) (OUTPUT) RON = 20 Ω, CL = 15 pF 0.3 tpd (1) Propagation delay time SDA or SCL SDn or SCn ns RON = 20 Ω, CL = 50 pF 1 tiv Interrupt valid time(2) INTn INT 4 μs tir Interrupt reset delay time(2) INTn INT 2 μs (1) The propagation delay is the calculated RC time constant of the typical ON-state resistance of the switch and the specified load capacitance, when driven by an ideal voltage source (zero output impedance). (2) Data taken using a 4.7-k Ω pullup resistor and 100-pF load (see Figure 13) over recommended operating free-air temperature range (unless otherwise noted) (see Figure 13) PARAMETER MIN MAX UNIT tPWRL Required low-level pulse duration of INTn inputs(1) 1 μs tPWRH Required high-level pulse duration of INTn inputs(1) 0.5 μs tWL Pulse duration, RESET low 4 ns trst (2) RESET time (SDA clear) 500 ns tREC Recovery time from RESET to start 0 ns (1) The device has interrupt input rejection circuitry for pulses less than the listed minimum. (2) trst is the propagation delay measured from the time the RESET pin is first asserted low to the time the SDA pin is asserted high, signaling a stop condition. It must be a minimum of tWL.
