The HD74LV2GT125AUSE-E is a dual single-bit non-inverting bus transceiver with 3-state outputs, manufactured by Renesas Electronics America. This device contains two independent channels, each functioning as a buffer that can be enabled or disabled. When enabled, the output follows the input; when disabled, the output is in a high-impedance state, effectively disconnecting it from the bus. It is part of the LV family, designed for low-voltage operation (typically 3.3V) and high-speed performance.

Applications

• Bus interfacing: Used to connect devices to a shared bus, enabling or disabling data flow.
• Data isolation: Isolates different parts of a system by enabling or disabling signal paths.
• Memory interfacing: Used in memory systems to control access to memory devices.
• Level shifting: Can be used to interface between different voltage levels (with careful consideration of specifications).
• Portable electronics: Employed in battery-powered devices where low power consumption is critical.

Features

• Dual single-bit transceiver: Contains two independent buffer channels.
• Non-inverting: Output signal has the same polarity as the input signal.
• 3-state outputs: Output can be high, low, or high-impedance (disabled).
• Low-voltage operation: Designed for operation at low voltages, typically 3.3V.
• High-speed performance: Offers fast switching speeds.
• Low power consumption: Requires minimal power compared to other logic families.

Benefits

• Simplified bus management: Enables easy control of data flow on a shared bus.
• Reduced system loading: 3-state outputs minimize loading on the bus when disabled.
• Extended battery life: Low power consumption extends battery life in portable devices.
• Improved system performance: High-speed performance allows for faster data transfer.
• Compact solution: Small package size allows for use in space-constrained applications.

Additional Details

The HD74LV2GT125AUSE-E is supplied in an 8-pin US8 (Ultra Small Outline Package). Each channel has an output enable (OE) input. When OE is low, the output is enabled and follows the input. When OE is high, the output is in a high-impedance state. The typical propagation delay is around 4 ns at VCC=3.3V. The input voltage range is from 0V to VCC. The operating temperature range is typically -40°C to +85°C.
