1 / 12 page SN74LVTH652EP 3.3V ABT OCTAL BUS TRANSCEIVER AND REGISTER WITH 3STATE OUTPUTS SCBS776 − NOVEMBER 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Controlled Baseline − One Assembly/Test Site, One Fabrication Site D Enhanced Diminishing Manufacturing Sources (DMS) Support D Enhanced Product-Change Notification D Qualification Pedigree† D Supports Mixed-Mode Signal Operation (5-V Input and Output Voltages With 3.3-V VCC) D Supports Unregulated Battery Operation Down To 2.7 V D Typical VOLP (Output Ground Bounce) <0.8 V at VCC = 3.3 V, TA = 25°C D Ioff and Power-Up 3-State Support Hot Insertion † Component 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 compound life. Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits. D Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors D Latch-Up Performance Exceeds 500 mA Per JESD 17 D ESD Protection Exceeds JESD 22 − 2000-V Human-Body Model (A114-A) − 200-V Machine Model (A115-A) description/ordering information This bus transceiver and register is designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment. The SN74LVTH652 consists of bus-transceiver circuits, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the data bus or from the internal storage registers. Output-enable (OEAB and OEBA) inputs are provided to control the transceiver functions. Select-control (SAB and SBA) inputs are provided to select whether real-time or stored data is transferred. The circuitry used for select control eliminates the typical decoding glitch that occurs in a multiplexer during the transition between real-time and stored data. A low input selects real-time data and a high input selects stored data. Figure 1 illustrates the four fundamental bus-management functions that can be performed with the SN74LVTH652 device.
