1 / 6 page Preliminary © 2001 Fairchild Semiconductor Corporation DS500429 www.fairchildsemi.com February 2001 Revised August 2001 74LVTH322374 Low Voltage 32-Bit D-Type Flip-Flop with 3-STATE Outputs and 25 Ω Series Resistors in the Outputs (Preliminary) General Description The LVTH322374 contains thirty-two non-inverting D-type flip-flops with 3-STATE outputs and is intended for bus ori- ented applications. The device is byte controlled. A buff- ered clock (CP) and Output Enable (OE) are common to each byte and can be shorted together for full 32-bit opera- tion. The LVTH322374 is designed with equivalent 25 Ω 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 drivers, and bus transceiv- ers/transmitters. The LVTH322374 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs. These flip-flops are designed for low voltage (3.3V) VCC applications, but with the capability to provide a TTL inter- face to a 5V environment. The LVTH322374 is 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 s Live insertion/extraction permitted s Power Up/Power Down high impedance provides glitch- free bus loading s Outputs include equivalent series resistance of 25 Ω to make external termination resistors unnecessary and reduce overshoot and undershoot 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.
