The SN5407 and SN7407 have minimum breakdownvoltages of 30 V, and the SN5417 and SN7417 have minimum breakdown voltages of 15 V. The maximum sinkcurrent is 30 mA for the SN5407 and SN5417 and 40 mA for the SN7407 and SN7417. These devices perform Boolean function Y = A in positive logic. These circuits are completely compatible with most TTL families. Inputs are diode clamped to minimizetransmission-line effects, which simplifies design. Typical power dissipation is 145 mW, and averagepropagation delay time is 14 ns. ORDERING INFORMATION TOP-SIDE
