Overview

The LVT162245 and LVTH162245 contains 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 LVT162245 and LVTH162245 are designed with equivalent 25ohm 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 LVTH162245 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 LVT162245 and LVTH162245 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.

  • This product is general usage and suitable for many different applications.
  • 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 (74LVTH162245), also available without bushold feature (74LVT162245).
  • Live insertion/extraction permitted
  • Power Up/Down high impedance provides glitch-free bus loading
  • A Port outputs include equivalent series resistance of 25ohm 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
  • Functionally compatible with the 74 series 162245
  • Latch-up performance exceeds 500 mA
  • ESD performance:Human-body model > 2000VMachine model > 200VCharged-device model > 1000V
  • Also packaged in plastic Fine Pitch Ball Grid Array (FBGA)
