TC74AC240FT

• High speed: t_pd = 4.0 ns (typ.) at V_CC = 5 V
• Low power dissipation: I_CC = 8 A (max) at Ta = 25°C
• High noise immunity: V_NIH = V_NIL = 28% V_CC (min)
• Symmetrical output impedance: |I_OH| = I_OL = 24 mA (min)
                                                     Capability of driving 50 transmission lines.
• Balanced propagation delays: t_pLH −∼ t_pHL
• Wide operating voltage range: V_{CC (opr)} = 2 to 5.5 V
• Pin and function compatible with 74F240/244

The TC74AC240FT and 244 are advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate and double-layer metal wiring C2MOS technology.

They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.

The TC74AC240FT is an inverting 3-state buffer while the 74AC244 is non-inverting. Both devices have two active-low output enables.

These devices are designed to be used in such applications as 3-state memory address drivers.

All TC74AC240FT inputs are equipped with protection circuits against static discharge or transient excess voltage.
