To address the need for a complete low-voltage interface solution, Texas Instruments has developed a new generation of logic devices capable of mixed-mode operation. The LVT series relies on a state-of-the-art submicron BiCMOS process to provide up to a 90% reduction in static power dissipation over ABT. LVT devices solve the system need for a transparent seam between the low-voltage and 5-V secti - LVT-to-LVTH ConversionPDF, 84 Kb, Archivo publicado: dic 8, 1998
Original LVT devices that have bus hold have been redesigned to add the High-Impedance State During Power Up and Power Down feature. Additional devices with and without bus hold have been added to the LVT product line. Design guidelines and issues related to the bus-hold features, switching characteristics, and timing requirements are discussed.
