Product Summary
The SN74AVC16T245DGGR is a 16-bit dual-supply bus transceiver. The SN74AVC16T245DGGR uses two separate configurable power-supply rails. The SN74AVC16T245DGGR is optimized to operate with Vcca/Vccb set at 1.4 V to 3.6 V. The SN74AVC16T245DGGR 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.
Parametrics
SN74AVC16T245DGGR absolute Maximum Ratings: (1) Supply voltage range, Vcca and Vccb: -0.5 V to 4.6 V; (2) Input voltage range, V, I/o ports (A port) : -0.5 V to 4.6 VI: -65°C to +125°; (3) Voltage with Respect to Ground: VCC= -0.5V to +4V, A9, OE#, and RESET#= -0.5V to +12.5V, All other pins= -0.5V to Vcc+0.5V; (4) Output Short Circuit Current: 200mA.
Features
SN74AVC16T245DGGR features: (1) Control Inputs VIH/VIL Levels Are Referenced to Vcca Voltage; (2) Vcc Isolation Feature - If Either Vcc Input Is at GND, Both Ports Are in the High-Impedance State; (3) Overvoltage-Tolerant Inputs/Outputs Allow Mixed-Voltage-Mode Data Communications; (4) Fully Configurable Dual-Rail Design Allows Each Port to Operate Over the Full 1.2-V to 3.6-V Power-Supply Range; (5) I Supports Partial-Power-Down Mode off Operation; (6) I/Os Are 4.6-V Tolerant; (7) Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II; (8) ESD Protection Exceeds JESD 22.
