Detailed Description

8-bit TTL-to-BTL registered transceiver designed for high-speed backplane and bus interfaces

Surface-mount 52-QFP package with 10 mm x 10 mm body

Operates from a single 5 V supply, 4.75 V to 5.25 V range

Commercial temperature grade, 0°C to 70°C

RoHS3 compliant

Series 74FB, base product number 74FB2033

Key Features

8-bit bidirectional registered transceiver for clean data handoff

TTL input-compatible with BTL bus-level outputs

Edge-triggered internal registers for timing control and data latching

High-speed operation optimized for 5 V systems

Tri-state control for bus isolation

Surface-mount QFP with gull‑wing leads for reliable soldering

RoHS3 compliant materials

Key Advantages

Stable timing thanks to built-in registers, reducing bus contention and skew

Clean TTL-to-BTL level translation for backplane systems

Simple 5 V supply reduces power architecture complexity

Compact 52‑QFP saves board space compared to through-hole options

Drop-in fit within the 74FB family for consistent design behavior

Packaging

Shipment format: Tape and Reel TR for automated placement

IC package: 52‑QFP, 10 mm x 10 mm body, gull‑wing leads, surface mount

Pin count and configuration: 52 leads arranged around the perimeter for bus and control pins (refer to datasheet pinout)

Materials: Molded epoxy body, copper leadframe, tin-based lead finish, RoHS3 compliant

Thermal characteristics: Commercial operating range 0°C to 70°C; actual thermal resistance depends on PCB layout and airflow; follow TI reflow and thermal guidelines

Electrical properties: 5 V supply 4.75 V to 5.25 V, TTL input thresholds, BTL bus-level outputs, 8-bit wide data path, tri-state and register control signals

Lifecycle

Status: Mature 74FB-series logic. Availability can vary by region. Some package options may be limited or NRND. Check current status with Y-IC for the latest information.

Equivalent or alternative models:

- Same base device in other TI package or order-code variants within the SN74FB2033A family (package codes may differ; verify pinout and mechanicals)

- Related TI 5 V bus transceivers for general TTL buses (not BTL and not drop-in): SN74ABT623, SN74ABT245, SN74ALS245 (use only if BTL is not required and revalidate timing, levels, and control)

- For exact cross and drop‑in, contact Y-IC to review footprint, timing, and bus-level requirements

If you need confirmed drop-in alternatives or lifecycle dates, please contact our sales team via the Y-IC website for a detailed cross-reference and availability check
