.ti. SN74ALVC164245-EP 16-BIT 2.5-V TO 3.3-V/3.3-V TO 5-V LEVEL-SHIFTING TRANSCEIVER WITH 3-STATE OUTPUTS SCAS774A - JUNE 2004 - REVISED SEPTEMBER 2005 Features - Controlled Baseline - One Assembly/Test Site, One Fabrication Site - Enhanced Diminishing Manufacturing Sources (DMS) Support - Enhanced Product-Change Notification - Qualification Pedigree(1) - Member of the Texas Instruments Widebus™ Family - Max tpd of 5.8 ns at 3.3 V - ±24-m A Output Drive at 3.3 V - Control Inputs VIH/VIL Levels Are Referenced to VCCA Voltage - Latch-Up Performance Exceeds 250 m A Per JESD 17 (1) ponent qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range. This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold pound life. Such qualification testing should not be viewed as justifying use of this ponent beyond specified performance and environmental limits.

B port has VCCB, which is set to operate at 3.3 V and 5 V. A port has VCCA, which is set to operate at 2.5 V and 3.3 V. This allows for translation from a 2.5-V to a 3.3-V environment, and vice versa, or from a 3.3-V to a 5-V environment, and vice versa. The SN74ALVC164245 is designed for asynchronous munication between data buses. The control circuitry (1DIR, 2DIR, 1OE,...
