74LVT16240MEAX集成電路（IC）的緩沖器驅(qū)動(dòng)器接收器收發(fā)器規(guī)格書(shū)PDF中文資料

General Description

The LVT16240 and LVTH16240 contain sixteen inverting buffers with 3-STATE outputs designed to be employed as a memory and address driver, clock driver, or bus-oriented transmitter/receiver. The device is nibble controlled.

Individual 3-STATE control inputs can be shorted together for 8-bit or 16-bit operation.

The LVTH16240 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.

These buffers and line drivers are designed for low-voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT16240 and LVTH16240 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.
