74LVTH16245MEA集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器規(guī)格書PDF中文資料

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.

Features

■ Input and output interface capability to systems at 5V VCC

pull-up resistors to hold unused inputs (74LVTH16245),

also available without bushold feature (74LVT16245).

■ Live insertion/extraction permitted

■ Power Up/Down high impedance provides glitch-free bus loading

■ Outputs source/sink -32 mA/+64 mA

■ Functionally compatible with the 74 series 16245

■ Latch-up performance exceeds 500 mA

■ ESD performance:

Human-body model > 2000V

Machine model > 200V
