CMOS Digital Integrated Circuits Silicon Monolithic  
74VHCT245AFT  
1. Functional Description  
Octal Bus Transceiver  
2. General  
The 74VHCT245AFT is an advanced high speed CMOS OCTAL BUS TRANSCEIVER fabricated with silicon  
gate C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while  
maintaining the CMOS low power dissipation.  
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.  
The input voltage are compatible with TTL output voltage.  
This device may be used as a level converter for interfacing 3.3 V to 5 V system.  
Input protection and output circuit ensure that 0 V to 5.5 V can be applied to the input and output (Note) pins  
without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and  
input/output voltages such as battery back up, etc.  
Note: Output in off-state  
3. Features  
(1) High speed: Propagation delay time = 4.9 ns (typ.) at VCC = 5 V  
(2) Quiescent supply current: ICC = 4 µA (max) at Ta = 25  
(3) Compatible with TTL inputs: VIL = 0.8 V (max)  
VIH = 2.0 V (min)  
(4) Power-down protection is provided on all inputs and outputs  
(5) Balanced propagation delays: tPLH tPHL  
(6) Low noise: VOLP = 1.5 V (max)  
(7) Pin and function compatible with the 74 series (74ACT/HCT/AHCT etc.) 245 type.  
Note: Do not apply a signal to any bus terminal when it is in the output mode. Damage may result.  
All floating (high impedance) bus terminals must have their input levels fixed by means of pull up or pull down  
resistors.
