Features
 High speed: tpd = 14 ns (typ.) at VCC = 6 V
 Low power dissipation:
ICC = 4 A (max.) at TA = 25 °C
 High noise immunity:
VNIH = VNIL = 28% VCC (min.)
 Symmetrical output impedance:
|IOH| = IOL = 4 mA (min.)
 Balanced propagation delays: tPLH  tPHL
 Wide operating voltage range:
VCC (OPR) = 2 to 6 V
 Pin and function compatible with 74 series 42
