Description: The TC74HC240P is an 8-bit inverting buffer/line driver with 3-state outputs from Toshiba.
Features:
High speed: tpd = 8.0 ns (typ.) at VCC = 5 V
Low power dissipation: ICC = 1.0 μA (max) at Ta = 25°C
High noise immunity: VNIH = VNIL = 28% VCC (min)
Outputs can be connected to other TC74HC240P devices without external bus-hold circuitry
Outputs source/sink 24 mA
Outputs can be placed in high impedance state
Applications:
Bus buffer registers
Bus or port-expanders
Data transmission between registers
