1 / 6 page Preliminary © 2001 Fairchild Semiconductor Corporation DS500434 www.fairchildsemi.com January 2001 Revised August 2001 74LVT32244 • 74LVTH32244 Low Voltage 32-Bit Buffer/Line Driver with 3-STATE Outputs (Preliminary) General Description The LVT32244 and LVTH32244 contain thirty-two non- 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 con- trolled. Individual 3-STATE control inputs can be shorted together for 8-bit, 16-bit, or 32-bit operation. The LVTH32244 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 LVT32244 and LVTH32244 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation Features s Input and output interface capability to systems at 5V VCC s Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH32244), also available without bushold feature (74LVT32244). s Live insertion/extraction permitted s Power Up/Down high impedance provides glitch-free bus loading s Outputs source/sink −32 mA/+64 mA s ESD performance: Human-body model > 2000V Machine model > 200V Charged-device model > 1000V s Packaged in plastic Fine-Pitch Ball Grid Array (FBGA) (Preliminary) Ordering Code: Note 1: BGA package available in Tape and Reel only.
