Product data sheet Rev. 3 — 5 January 2012 5 of 16 NXP Semiconductors CBT3245A Octal bus switch [1] All typical values are at VCC =5V, 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 An and the Bn terminals at the indicated current through the switch. ON resistance is determined by the lowest voltage of the two (An or Bn) terminals. 10. Dynamic characteristics [1] The propagation delay is the calculated RC time constant of the typical ON resistance of the switch and the specified load capacitance, when driven by an ideal voltage source (zero output impedance). [2] tpd is the same as tPLH and tPHL. ten is the same as tPZL and tPZH. tdis is the same as tPLZ and tPHZ. RON ON resistance VCC =4.5 V; VI =0V; II =64 mA [3] -5 7 VCC =4.5 V; VI =0V; II =30 mA [3] -5 7 VCC =4.5 V; VI =2.4 V; II = 15 mA [3] -10 15 Table 6. Static characteristics …continued Voltages are referenced to GND (ground = 0 V). Symbol Parameter Conditions Tamb = 40 C to +85 C Unit Min Typ[1] Max Table 7. Dynamic characteristics Voltages are referenced to GND (ground = 0 V). For test circuit see Figure 7. Symbol Parameter Conditions Tamb = 40 C to +85 C Unit Min Max tpd propagation delay An, Bn to Bn, An; see Figure 5 [1][2] VCC = 5.0 V 0.5 V - 0.25 ns ten enable time OE to An or Bn; see Figure 6 [2] VCC = 5.0 V 0.5 V 1.0 5.9 ns tdis disable time OE to An or Bn; see Figure 6 [2] VCC = 5.0 V 0.5 V 1.0 6.0 ns |
