Product Summary

The SN74AVC32T245ZKER is a 32-bit dual-supply bus transceiver with configurable voltage translation and 3-state outputs. It is optimized to operate with VCCA/VCCB set at 1.4 V to 3.6 V. The SN74AVC32T245ZKER is operational with VCCA/VCCB as low as 1.2 V. 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. 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. The SN74AVC32T245ZKER is designed for asynchronous communication between data buses.

Parametrics

SN74AVC32T245ZKER absolute maximum ratings: (1)Supply voltage range, VCCA and VCCB: -0.5 V to 4.6 V; (2)Input voltage range, VI: I/O ports (A port): -0.5 V to 4.6 V; I/O ports (B port): -0.5 V to 4.6 V; Control inputs: -0.5 V to 4.6 V; (3)Voltage range applied to any output in the high-impedance or power-off state, VO: A port: -0.5 V to 4.6 V; B port: -0.5 V to 4.6 V; (4)Input clamp current, IIK (VI < 0): -50 mA; (5)Output clamp current, IOK (VO < 0): -50 mA; (6)Continuous output current, IO: ±50 mA; (7)Continuous current through each VCCA, VCCB, and GND: ±100 mA; (8)Package thermal impedance, θJA (see Note 3): GKE/ZKE package: 40℃/W; (9)Storage temperature range, Tstg: -65℃ to 150℃.

Features

SN74AVC32T245ZKER features: (1)Member of the Texas Instruments Widebus+ Family; (2)Control Inputs VIH/VIL Levels Are Referenced to VCCA Voltage; (3)VCC Isolation Feature . If Either VCC Input Is at GND, Both Ports Are in the High-Impedance State; (4)Overvoltage-Tolerant Inputs/Outputs Allow Mixed-Voltage-Mode Data Communications; (5)Fully Configurable Dual-Rail Design Allows Each Port to Operate Over the Full 1.2-V to 3.6-V Power-Supply Range; (6)Ioff Supports Partial-Power-Down Mode Operation; (7)I/Os Are 4.6-V Tolerant.
