TC74LVXC3245FS
Dual Supply Octal Configurable Voltage Interface Bus Transceiver
The TC74LVXC3245FS is a dual supply, advanced high-speed
CMOS octal configurable voltage interface bus transceiver
fabricated with silicon gate CMOS technology.
Designed for use as an interface between a 3.3 V bus and a
3.3V to 5 V bus in mixed 3.3 V/5 V supply systems’ it achieves
high-speed operation while maintaining the CMOS low power
dissipation.
It is intended for 2 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 buses are effectively isolated. The A-port
interfaces with the 3.3-V bus, the B-port with the 3.3V to 5V bus.
Weight: 0.14 g (typ.)
This device will allow the VCCB voltage source pin and I/O pins
on the B port to float when G is “H”.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features
· Bi-directional interface between 3 V and 5 V buses
· High-speed: tpd = 8.5 ns (max)
www.DataSheet4U.com(VCCA = 3.3 V, VCCB = 5.0 V)
· Low power dissipation: ICC = 8 µA (max) (Ta = 25°C)
· Symmetrical output impedance: IOUTA = ±24 mA (min)
IOUTB = ±24 mA (min)
(VCCA = VCCB = 3.0 V)
· Low noise: VOLP = 1.5 V (max)
· Flexible VCCB operating range
· Allows B port and VCCB to float simultaneously when G is “H”
· Package: SSOP (shrink small outline package)
Note 1: Do not apply a signal to any bus pins when it is in the output mode. Damage may result.
All floating (high impedance) bus pin must have their input levels fixed by means of pull-up or pull-down
resistors.
