Product details
Overview
TC7SH125F,LJ(CT) from Toshiba Electronic Devices & Storage Corporation is a single-channel CMOS bus buffer with 3-state output, designed for bidirectional data bus isolation in low-voltage digital systems. It operates across 2.0–5.5 V supply, delivers 3.8 ns typical propagation delay at 5.0 V/15 pF, and supports automotive-grade temperature range (−40 to 125 °C) per AEC-Q100 Rev. H compliance.
For engineers reviewing the TC7SH125F,LJ(CT) datasheet, TC7SH125F,LJ(CT) pinout, TC7SH125F,LJ(CT) application, or TC7SH125F,LJ(CT) equivalent, this device is selected for high-noise-immunity bus interfacing in automotive control modules, industrial PLC I/O expansion, and portable embedded systems requiring 5.5 V-tolerant inputs and ultra-low quiescent current (≤2.0 µA).
Technical Context
The TC7SH125F,LJ(CT) implements a non-inverting 3-state buffer with active-high output enable (OE), enabling precise control of data flow on shared buses. Its input structure accepts voltages up to 5.5 V independent of VCC, allowing level translation between 3.3 V and 5 V domains without external components.
It features rail-to-rail output drive capability (VOH ≥ 4.4 V, VOL ≤ 0.1 V at VCC = 4.5 V/8 mA), high noise immunity (VNIH/VNIL ≥ 28 % VCC), and guaranteed operation over −40 to 125 °C - validated specifically for ordering suffix J(CT).

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Same SOT-25 package; 1.65–5.5 V VCC; 3.7 ns tPD (VCC = 3.3 V); not AEC-Q100 qualified | Limited to commercial/industrial use; lacks automotive qualification and extended temperature validation | Select when cost sensitivity outweighs automotive qualification requirements |
| 74AUP1G125GW,125 | Same footprint; 0.8–3.6 V VCC only; 6.3 ns tPD (VCC = 3.3 V); ICC = 0.9 µA max; AEC-Q100 Grade 2 (−40 to 105 °C) | Lower voltage ceiling restricts use in 5 V systems; narrower temp range than TC7SH125F,LJ(CT) | Prefer for ultra-low-power 3.3 V-only designs where 125 °C operation is unnecessary |

FAQ
What is the operating temperature range specified for TC7SH125F,LJ(CT)?
The TC7SH125F,LJ(CT) is rated for −40 to 125 °C continuous operation, as confirmed by AEC-Q100 Rev. H qualification and electrical testing across that full range. This specification applies specifically to parts with the J(CT) suffix, distinguishing it from standard-grade variants limited to −40 to 85 °C.
Does TC7SH125F,LJ(CT) support 5 V input signals when powered at 3.3 V?
Yes, TC7SH125F,LJ(CT) features 5.5 V tolerant inputs, meaning it reliably accepts 0–5.5 V input voltages regardless of VCC setting (2.0–5.5 V). This allows safe interfacing of 5 V sensors or legacy peripherals to a 3.3 V-powered microcontroller bus without external level shifters.
What is the maximum output drive capability of TC7SH125F,LJ(CT) at 4.5 V supply?
At VCC = 4.5 V, TC7SH125F,LJ(CT) guarantees ±8 mA output drive strength - delivering VOH ≥ 4.4 V and VOL ≤ 0.1 V under those conditions. This supports driving multiple 74LVC inputs or standard TTL loads while maintaining signal integrity.
Is TC7SH125F,LJ(CT) pin-compatible with other SOT-25 single-buffer devices?
TC7SH125F,LJ(CT) uses the standard SOT-25 (JEDEC MO-178AB) pinout: Pin 1 = A (input), Pin 2 = GND, Pin 3 = Y (output), Pin 4 = VCC, Pin 5 = OE (active-high). This matches industry-standard pin assignments for single 3-state buffers, enabling mechanical compatibility with SN74LVC1G125 and 74AUP1G125 footprints.
How does the 3-state output behavior work on TC7SH125F,LJ(CT)?
TC7SH125F,LJ(CT) asserts its output Y = A when OE is high; when OE is low, Y enters high-impedance (Z) state, electrically disconnecting the output from the bus. This behavior is explicitly defined in the truth table and verified across all operating voltages and temperatures, enabling clean bus sharing in multi-master systems.
