Description

SN74AVC4T234ZSUR is a 4‑bit bidirectional voltage-level translator from Texas Instruments. It provides four independent translation channels (A1–A4 on VCCA side and B1–B4 on VCCB side) to connect two voltage domains with different logic levels. A control input (DIR) selects the data direction (A→B or B→A), and an enable/tri‑state control lets you disconnect both sides when needed. It’s designed for low power, fast switching, and low leakage, making it suitable for interfacing microcontrollers, memory, sensors, and peripherals across voltage domains (for example 1.8V/3.3V to 5V). The ZSUR suffix indicates a specific RoHS-compliant package variant (a compact 14‑pin small-outline/VSSOP style). In short, use it to safely translate logic levels between devices operating at different supply voltages with controlled direction and tri-state capability.

Features

SN74AVC4T234ZSUR features (concise):
- 4-bit bidirectional voltage-level translator/buffer with 3-state outputs
- Dual-supply operation: A-side (VCCA) and B-side (VCCB) for level shifting between domains
- DIR input to choose data flow (A→B or B→A)
- OE (output enable) to tri-state the 4 outputs
- Ioff for partial-power-down protection (no back-powering when one side is powered down)
- CMOS inputs with TTL-compatible thresholds; low static/dynamic power
- Fast switching with low on-resistance
- ESD and latch-up protection
- RoHS-compliant packaging; available in a 20-pin package variant (ZSUR)

Pinout

- Pin count: 16 pins (ZSUR package, e.g., VSSOP/SOIC-16 style).
- Function: 4-bit dual-supply translating buffer/level shifter with direction control. It provides four bidirectional channels (A1–A4 on VCCA side and B1–B4 on VCCB side) and translates between the two voltage domains. Includes a direction control input (DIR) and an enable/input-output control (OE) to tri-state the outputs.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: TI is a global semiconductor company that designs and manufactures analog, mixed-signal, and digital integrated circuits for automotive, industrial, communications, and consumer electronics markets.

Application

- Bidirectional level shifting between two voltage domains (eg, 1.2–3.3 V, 1.8–3.3 V)
- Interface bridging for microcontrollers, sensors, memories, and peripherals with different logic levels
- I/O expansion and signal routing in portable/consumer electronics
- High-speed digital interfaces in mixed-voltage systems
- Automotive and industrial applications with multi-rail signaling

Package

Package type: 20-pin VSSOP (Very-Small-Outline) package. The TI suffix ZSUR indicates the RoHS-compliant VSSOP-20 variant.
