74AHC240; 74AHCT240

Octal buffer/line driver; inverting; 3-state

[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; ten is the same as tPZH and tPZL; tdis is the same as tPLZ and tPHZ.

[3]

CPD is used to determine the dynamic power dissipation (PD in W).

PD =CPD  VCC2  fi  N + (CL  VCC2  fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

CL = output load capacitance in pF;

VCC = supply voltage in V;

N = number of inputs switching;
