Product data sheet Rev. 02 — 9 November 2007 8 of 16 NXP Semiconductors 74AHC157; 74AHCT157 Quad 2-input multiplexer [1] Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V). [2] tpd is the same as tPLH and tPHL. [3] CPD is used to determine the dynamic power dissipation PD (µW). PD =CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts. CPD power dissipation capacitance CL = 50 pF; fi = 1 MHz; VI = GND to VCC [3] 4 outputs switching via S - 31 - - - - - pF 1 outputs switching via I - 13 - - - - - pF For type 74AHCT157 tpd propagation delay nI0, nI1 to nY; see Figure 7 [2] VCC = 4.5 V to 5.5 V CL = 15 pF - 3.2 6.4 1.0 7.5 1.0 8.0 ns CL = 50 pF - 4.6 8.7 1.0 9.8 1.0 11.0 ns S to nY; see Figure 7 VCC = 4.5 V to 5.5 V CL = 15 pF - 3.7 8.6 1.0 10.0 1.0 11.0 ns CL = 50 pF - 5.2 10.4 1.0 12.0 1.0 13.0 ns E to nY; see Figure 8 [2] VCC = 4.5 V to 5.5 V CL = 15 pF - 4.7 8.1 1.0 9.5 1.0 10.5 ns CL = 50 pF - 6.7 10.6 1.0 12.0 1.0 13.5 ns CPD power dissipation capacitance CL = 50 pF; fi = 1 MHz; VI = GND to VCC [3] 4 outputs switching via S - 41 - - - - - pF 1 outputs switching via I - 16 - - - - - pF Table 7.
