74LVT322245规格书详情
General Description
The LVT322245 and LVTH322245 contain thirty-two noninverting bidirectional buffers with 3-STATE outputs and are intended for bus oriented applications. The device is byte controlled. Each byte has separate control inputs which can be shorted together for full 32-bit operation. The T/R inputs determine the direction of data flow through the device. The OE inputs disable both the A and B ports by placing them in a high impedance state.
The LVT322245 and LVTH322245 are designed with equivalent 25Ω series resistance in both the HIGH and LOW states on the A Port outputs. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus transceivers/transmitters. The LVTH322245 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.
These non-inverting transceivers are designed for low-voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT322245 and LVTH322245 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.
Features
■ Input and output interface capability to systems at 5V VCC
■ Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH322245)
■ Also available without bushold feature (74LVT322245)
■ Live insertion/extraction permitted
■ Power Up/Power Down high impedance provides glitch-free bus loading
■ A Port outputs include equivalent series resistance of 25Ω making external termination resistors unnecessary and reducing overshoot and undershoot
■ A Port outputs source/sink ±12 mA
B Port outputs source/sink −32 mA/+64 mA
■ ESD performance:
Human-body model > 2000V
Machine model > 200V
Charged-device model > 1000V
■ Packaged in plastic Fine-Pitch Ball Grid Array (FBGA)
