Overview
Preliminary 74LVTH32952 Low Voltage 32-Bit Registered Transceiver with 3-STATE Outputs (Preliminary) September 2000 Revised August 2001 74LVTH32952 Low Voltage 32-Bit Registered Transceiver with 3-STATE Outputs (Preliminary) General Description The LVTH32952 is a 32-bit registered transceiver.
Four 8-bit back to back registers store data flowing in both directions between two bidirectional buses.
Separate clock, clock enable, and output enable signals are provided for each register.
The LVTH32952 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.
The registered transceiver is designed for low voltage (3.
3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment.
The LVTH32952 is fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining 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/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: Order Number 74LVTH32952GX (Note 1) Package Number BGA114A (Preliminary) Package Description 114-Ball Fine-Pitch Ball Grid Array (FBGA), JEDEC MO-205, 5.
5mm Wide [TAPE and REEL] Note 1: BGA package available in Tape and Reel only.
