Product Summary

The SN74AVCH32T245ZKER is a 16-bit (dual-octal) noninverting bus transceiver. It uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.4 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.4 V to 3.6 V. The SN74AVCH32T245ZKER is designed for asynchronous communication between data buses. The SN74AVCH32T245ZKER transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input.

Parametrics

SN74AVCH32T245ZKER 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 VCCA, VCCB, or GND: ±100 mA; (8)Storage temperature range, Tstg: -65℃ to 150℃.

Features

SN74AVCH32T245ZKER features: (1)Member of the Texas Instruments Widebus Family; (2)DOC Circuitry Dynamically Changes Output Impedance, Resulting in Noise Reduction Without Speed Degradation; (3)Dynamic Drive Capability Is Equivalent to Standard Outputs With IOH and IOL of ±24 mA at 2.5-V VCC; (4)Control Inputs VIH/VIL Levels are Referenced to VCCB Voltage; (5)If Either VCC Input Is at GND, Both Ports Are in the High-Impedance State; (6)Overvoltage-Tolerant Inputs/Outputs Allow Mixed-Voltage-Mode Data Communications; (7)Ioff Supports Partial-Power-Down Mode Operation; (8)Fully Configurable Dual-Rail Design Allows Each Port to Operate Over the Full 1.4-V to 3.6-V Power-Supply Range.
