CMOS Digital Integrated Circuits Silicon Monolithic  
74HCT245D  
1. Functional Description  
Octal Bus Transceiver  
2. General  
The 74HCT245D is high speed CMOS OCTAL BUS TRANSCEIVER fabricated with silicon gate C2MOS  
technology.  
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power  
dissipation.  
Its inputs are compatible with TTL, NMOS, and CMOS output voltage levels.  
It is intended for two-way asynchronous communication between data busses. The direction of data transmission  
is determined by the level of the DIR input.  
The enable input (G) can be used to disable the device so that the busses are effectively isolated.  
All inputs are equipped with protection circuits against static discharge or transient excess voltage.  
3. Features (Note)  
(1) High speed: tpd = 11 ns (typ.) at VCC = 5.5 V  
(2) Low power dissipation: ICC = 4.0 µA (max) at Ta = 25  
(3) Compatible with TTL outputs: VIL = 0.8 V(max)  
VIH = 2.0 V(min)  
(4) Wide interfacing ability: LSTTL, NMOS, CMOS  
(5) Balanced propagation delays: tPLH tPHL  
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 of pull-up or pull-down  
resistors.  
4. Packaging
