SCES693B – FEBRUARY 2008 – REVISED MAY 2008 4-BIT DUAL-SUPPLY BUS TRANSCEIVER WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS • Each Channel Has an Independent DIR Control • Latch-Up Performance Exceeds 100 mA Per Input JESD 78, Class II • Control Inputs V IH/VIL Levels Are Referenced to • ESD Protection Exceeds the Following Levels VCCA Voltage (tested per JESD 22) • Fully Configurable Dual-Rail Design Allows – 8000-V Human-Body Model (A114-A) Each Port to Operate Over the Full 1.2-V to – 250-V Machine Model (A115-A) 3.6-V Power-Supply Range – 1500-V Charged-Device Model (C101) • I/Os Are 4.6-V Tolerant • I off Supports Partial Power-Down-Mode Operation • Typical Data Rates – 380 Mbps (1.8-V to 3.3-V Translation) – 200 Mbps (<1.8-V to 3.3-V Translation) – 200 Mbps (Translate to 2.5 V or 1.8 V) – 150 Mbps (Translate to 1.5 V) – 100 Mbps (Translate to 1.2 V) This 4-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.2 V to 3.6 V. The SN74AVC4T774 is optimized to operate with VCCA/VCCB set at 1.4 V to 3.6 V. It is operational with VCCA/VCCB as low as 1.2 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
