Product details

Overview

TC7SZ34F(T5L,JF,T) from Toshiba Electronic Devices & Storage Corporation is a single-channel CMOS non-inverting buffer IC designed for signal conditioning and level translation in low-power digital systems. It delivers ±24 mA output drive at V_CC = 3.0 V, achieves 2.4 ns typical propagation delay at 5.0 V/50 pF, operates across 1.65–5.5 V supply, and supports automotive-grade temperature range (−40 to +125 °C) with AEC-Q100 Rev. H compliance - used in engine control unit I/O buffering and CAN transceiver interface logic.

For engineers reviewing the TC7SZ34F(T5L,JF,T) datasheet, TC7SZ34F(T5L,JF,T) pinout, TC7SZ34F(T5L,JF,T) application, or TC7SZ34F(T5L,JF,T) equivalent, key selection considerations include its 5.5 V-tolerant inputs, power-down protection outputs, high-speed operation under 1.8 V–5.5 V rails, and SOT-25 (SMV) package compatibility with space-constrained automotive and industrial PCB layouts.

Technical Context

This device implements a single-stage CMOS non-inverting buffer with rail-to-rail input voltage tolerance up to 5.5 V independent of V_CC, enabling mixed-voltage domain interfacing. Its output stage provides symmetrical ±24 mA drive capability at 3.0 V, supporting direct connection to TTL loads or downstream gate inputs without external pull-ups.

The TC7SZ34F(T5L,JF,T) features power-down protection: when V_CC = 0 V, outputs enter high-impedance state with ≤0.1 µA leakage, preventing back-driving of powered subsystems. It meets AEC-Q100 Rev. H stress testing requirements for automotive applications, including temperature cycling, HTOL, and ESD (HBM ≥2 kV).

Pinout & Package

TC7SZ34F(T5L,JF,T) uses the JEDEC-standard SOT-25 (SMV) 5-pin surface-mount package, measuring 2.9 × 1.6 × 1.1 mm with 14 mg typical weight. Pin assignment is verified per Toshiba's official top-view diagram.

Pin/Terminal	Circuit Role	Design Meaning
1	Input (A)	CMOS-compatible input accepting 0–5.5 V; internally biased; must be tied to V_CC or GND if unused
2	GND	Ground reference for all internal circuitry and output stage return path
3	Output (Y)	Push-pull CMOS output with ±24 mA drive; 5.5 V power-down protection active when V_CC = 0 V
4	V_CC	Primary supply rail (1.65–5.5 V); powers internal logic and output stage; decoupling capacitor required
5	NC	No internal connection - electrically isolated; may be left floating or grounded per layout requirements

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar non-inverting buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G07DBVR	Open-drain output; no power-down protection; max V_CC = 5.5 V but inputs not 5.5 V tolerant above V_CC	Requires external pull-up for high-level assertion; unsuitable for hot-swap or power-gated subsystems	Select only when open-drain functionality and lower quiescent current (<1 µA) outweigh need for push-pull drive and power-down safety
74AUP1G07GW,125	Lower V_CC range (0.8–3.6 V); 3.6 V max input; t_PD = 3.4 ns (typ.) at 3.3 V; AEC-Q100 Grade 2 (−40 to +105 °C)	Not rated for 125 °C operation; incompatible with under-hood automotive locations requiring full Grade 0	Prefer for portable battery-powered devices where ultra-low ICC (<0.5 µA) and sub-1 V operation are critical

Compared with SN74LVC1G07DBVR and 74AUP1G07GW,125, the TC7SZ34F(T5L,JF,T) uniquely combines 5.5 V input tolerance, push-pull output with power-down protection, and full AEC-Q100 Grade 0 qualification - making it the only option among the three suitable for hot-swap-capable automotive body controllers operating at 125 °C.

FAQ

What is the maximum operating temperature for TC7SZ34F(T5L,JF,T)?

The TC7SZ34F(T5L,JF,T) is rated for continuous operation from −40 °C to +125 °C, fully compliant with AEC-Q100 Rev. H Grade 0 requirements. This specification is confirmed in Toshiba's official datasheet Section 8 (Operating Ranges), where Topr = −40 to 125 °C is explicitly stated for ordering codes ending in "F" (including TC7SZ34F(T5L,JF,T)).

Does TC7SZ34F(T5L,JF,T) support 1.8 V logic levels?

Yes, TC7SZ34F(T5L,JF,T) operates reliably at V_CC = 1.8 V ±0.15 V, with guaranteed propagation delay ≤4.4 ns (max) and output drive sufficient for driving 10+ standard CMOS loads. Its VIH/VIL thresholds scale with V_CC (VIH ≥ 0.75×V_CC), ensuring correct recognition of 1.8 V logic highs and lows.

Is TC7SZ34F(T5L,JF,T) pin-compatible with other SOT-25 logic buffers?

TC7SZ34F(T5L,JF,T) uses standard SOT-25 pinout (Input–GND–Output–V_CC–NC), matching JEDEC MO-178AA. However, pin compatibility does not imply functional equivalence: unlike open-drain alternatives (e.g., SN74LVC1G07), TC7SZ34F(T5L,JF,T) provides push-pull output and power-down protection - requiring verification of load type and power sequencing in replacement scenarios.

What is the input voltage tolerance of TC7SZ34F(T5L,JF,T)?

TC7SZ34F(T5L,JF,T) features 5.5 V tolerant inputs, meaning it accepts input voltages from −0.5 V to +6.0 V regardless of V_CC setting (per Absolute Maximum Ratings Table). This allows safe interfacing with 5 V signals while operating from 1.8 V or 2.5 V supplies - a key differentiator versus standard LVC or AUP-series buffers.

How does the power-down protection feature work in TC7SZ34F(T5L,JF,T)?

When V_CC = 0 V, TC7SZ34F(T5L,JF,T) automatically places its output (Pin 3) in high-impedance state with ≤0.1 µA leakage current (per Section 9.2 DC Characteristics). This prevents back-driving of powered upstream circuits - a critical safety function in modular automotive systems where subsystems power up/down independently.
