74LVT16245MEAX数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

General Description
The LVT16245 and LVTH16245 contain sixteen non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. Each byte has separate control inputs which can be shorted together for full 16-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 LVTH16245 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 LVT16245 and LVTH16245 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation.
