TC74HC245AP Octal Bus Transceiver

• Octal Bus Transceiver TC74HC245AP/AF:3-State, Non-Inverting TC74HC640AP/AF:3-State, Inverting 2. General The TC74HC245A, TC74HC640A are high speed CMOS OCTAL BUS TRANSCEIVERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. They are intended fo.

Features

(Note) (1) High speed: tpd = 10 ns (typ.) at VCC = 5.0 V (2) Low power dissipation: ICC = 4.0 µA (max) at Ta = 25
� (3) High noise immunity: VNIH = VNIL = 28 % VCC (min) (4) Output drive capability: 15 LSTTL loads (5) Output current: |IOH|/IOL = 6 mA (min) (VCC = 4.5 V) (6) Balanced propagation delays: tPLH ≈ tPHL (7) Wide operating voltage range: VCC(opr) = 2 V to 6 V (8) Pin and function compatible with 74LS245/640. Note: Do not apply a signal to any bus pins when it is in the output mode. Damage may result. All floating (high impedance) bus pins must have their input levels fixed by means o.
