Toshiba Semiconductor and Storage TC7SH34F,LJ(CT

Overview

TC7SH34F,LJ(CT) from Toshiba Electronic Devices & Storage Corporation is a single-channel non-inverting CMOS buffer IC designed for signal conditioning and level translation in low-power digital systems. It operates across 2.0–5.5 V supply, delivers 3.8 ns typical propagation delay at 5.0 V/15 pF, supports AEC-Q100 (Rev. H) qualification, and features 5.5 V tolerant inputs - enabling use in automotive body control modules with mixed-voltage interfaces.

For engineers reviewing the TC7SH34F,LJ(CT) datasheet, TC7SH34F,LJ(CT) pinout, TC7SH34F,LJ(CT) application, or TC7SH34F,LJ(CT) equivalent, key selection criteria include its -40 to 85 °C operating temperature range (per J(CT) suffix), ultra-low 2.0 µA max ICC quiescent current, high noise immunity (28 % VCC min), and SOT-25 (SMV) 5-pin package compatibility with space-constrained PCB layouts.

Technical Context

The TC7SH34F,LJ(CT) implements a single-stage CMOS inverter-based buffer architecture with rail-to-rail input voltage tolerance up to 5.5 V independent of VCC. Its logic function is strictly non-inverting (A → Y), with guaranteed switching thresholds defined as VIH ≥ VCC × 0.7 and VIL ≤ VCC × 0.3 across all operating voltages.

It uses standard TTL-compatible output drive capability: VOH ≥ 4.4 V (at VCC = 4.5 V, IOH = –8 mA) and VOL ≤ 0.1 V (at VCC = 4.5 V, IOL = 8 mA), while maintaining input leakage current ≤ ±0.1 µA and input capacitance of 4 pF (typ.) - supporting high-speed signal integrity in fanout-limited nodes.

FAQ

What is the operating temperature range for TC7SH34F,LJ(CT)?

The TC7SH34F,LJ(CT) is rated for -40 to +85 °C operation, as confirmed by Toshiba's datasheet Note 2 and Operating Ranges table (Section 8). This range applies specifically to devices with the J(CT) suffix and is validated under AEC-Q100 Rev. H stress testing for automotive cabin and industrial control environments. The TC7SH34F,LJ(CT) does not support the -40 to +125 °C grade.

Does TC7SH34F,LJ(CT) support 5 V logic interfacing when powered from 3.3 V?

Yes - the TC7SH34F,LJ(CT) features 5.5 V tolerant inputs, allowing it to accept 0–5.5 V input signals regardless of VCC setting. When powered from 3.3 V, it correctly buffers 5 V inputs (e.g., from legacy sensors) while producing 3.3 V-compatible outputs. This eliminates external level-shifting circuitry and is explicitly verified in Section 2 Features (item 6) and Absolute Maximum Ratings.

What is the maximum output drive capability of TC7SH34F,LJ(CT)?

The TC7SH34F,LJ(CT) provides push-pull CMOS output drive up to ±8 mA, with VOH ≥ 4.4 V (at VCC = 4.5 V, IOH = –8 mA) and VOL ≤ 0.1 V (at VCC = 4.5 V, IOL = 8 mA), as specified in Section 9.1 DC Characteristics. This enables direct driving of optocoupler LEDs, small capacitive loads (<50 pF), and multiple 74LVC inputs without degradation in propagation delay.

Is TC7SH34F,LJ(CT) pin-compatible with other SOT-25 logic buffers?

No - the TC7SH34F,LJ(CT) uses a unique pinout with Pin 5 designated NC (no connect), unlike many SOT-25 buffers that assign Pin 5 as an enable or second channel. Substituting with SN74LVC1G07DBVR or 74AUP1G07GW would require PCB layout changes due to differing pin functions. Always verify pin assignment using Toshiba's "Pin Assignment (Top view)" diagram in Section 4.

What packaging and marking information identifies TC7SH34F,LJ(CT)?

The TC7SH34F,LJ(CT) is supplied in a JEDEC SOT-25 (SMV) package, marked with "7SH34" on the top surface per Toshiba's Marking section. The "J(CT)" suffix in the full part number denotes the tape-and-reel packaging format and confirms the -40 to +85 °C temperature grade. Weight is 14 mg (typ.), and dimensions are 2.9 × 1.6 × 1.1 mm - critical for automated placement verification and thermal modeling.
