1 / 6 page © 2005 Fairchild Semiconductor Corporation DS012490 www.fairchildsemi.com June 1999 Revised June 2005 74LVT162240 • 74LVTH162240 Low Voltage 16-Bit Inverting Buffer/Line Driver with 3-STATE Outputs and 25 : Series Resistors in the Outputs General Description The LVT162240 and LVTH162240 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. Indi- vidual 3-STATE control inputs can be shorted together for 8-bit or 16-bit operation. The LVT162240 and LVTH162240 are designed with equivalent 25 : series resistance in both the HIGH and LOW states of the output. This design reduces line noise in applications such as memory address drivers, clock driv- ers, and bus transceivers/transmitters. The LVTH162240 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs. These inverting 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 LVT162240 and LVTH162240 are fabricated with an advanced BiCMOS technology to achieve high speed oper- ation similar to 5V ABT while maintaining a low power dis- sipation. Features s Input and output interface capability to systems at 5V VCC s Outputs include equivalent series resistance of 25 : to make external termination resistors unnecessary and reduce overshoot and undershoot s Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH162240), also available without bushold feature (74LVT162240) s Live insertion/extraction permitted s Power Up/Down high impedance provides glitch-free bus loading s Functionally compatible with the 74 series 162240 s Latch-up performance exceeds 500 mA s ESD performance: Human-body model ! 2000V Machine model ! 200V Charged-device model ! 1000V Ordering Code: Note 1: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code. Note 2: Use this Order Number to receive devices in Tape and Reel.
