Octal Bus Transceiver
The TC74LVX245F/ FT is a high-speed CMOS octal bus
transceiver fabricated using silicon gate CMOS technology.
Designed for use in 3-V systems, it achieves high-speed operation
while maintaining the CMOS low power dissipation.
These devices are suitable for low-voltage and battery operated
systems.
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.
Features (Note)
• High-speed: t_pd = 4.7 ns (typ.) (V_CC = 3.3 V)
• Low power dissipation: I_CC = 4 μA (max) (Ta = 25°C)
• Input voltage level: V_IL = 0.8 V (max) (V_CC = 3 V)
V_IH = 2.0 V (min) (V_CC = 3 V)
• Balanced propagation delays: t_pLH ^∼− t_pHL
• Low noise: V_OLP = 0.8 V (max)
• Pin and function compatible with 74HC245

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.
A parasitic diode is formed between the bus and V_CC terminals. Therefore bus terminal can not be used to
interface 5-V to 3-V systems directly.
