Product details
Overview
TC7SET125F(TE85L,F) from Toshiba Electronic Devices & Storage Corporation is a single-channel 3-state bus buffer IC designed for high-speed digital signal routing in automotive and industrial control systems. It features 3.7 ns typical propagation delay at 5.0 V, 5.5 V tolerant inputs, and AEC-Q100 Rev. H qualification for automotive use.
For engineers reviewing the TC7SET125F(TE85L,F) datasheet, TC7SET125F(TE85L,F) pinout, TC7SET125F(TE85L,F) application, or TC7SET125F(TE85L,F) equivalent, key selection criteria include its -40 to 125 °C operating range, 2.0 µA max ICC at 25 °C, TTL-compatible input thresholds, and SOT-25 (SMV) package suitability for space-constrained PCB layouts.
Technical Context
The TC7SET125F(TE85L,F) implements a non-inverting 3-state buffer with active-low output enable (G), enabling bidirectional bus isolation in shared-data-path architectures. Its logic function supports high-impedance output state (Z) when G = H, and pass-through operation (Y = A) when G = L - confirmed by truth table and IEC symbol.
Designed for 4.5–5.5 V supply operation, it delivers VIH ≥ 2.0 V and VIL ≤ 0.8 V under all temperature conditions (-40 to 125 °C), ensuring robust noise margin against TTL-level drivers. Input tolerance up to 5.5 V allows interfacing with higher-voltage peripherals without level-shifting circuitry.
Key Specifications

The TC7SET125F(TE85L,F) uses a 5-pin SOT-25 (SMV) package with pinout: Pin 1 = A (input), Pin 2 = G (active-low enable), Pin 3 = GND, Pin 4 = Y (3-state output), Pin 5 = VCC. This layout is documented in Section 4 ("Marking and Pin Assignment") of the Toshiba datasheet Rev. 3.0.A.
Is TC7SET125F(TE85L,F) RoHS compliant?
Yes, TC7SET125F(TE85L,F) complies with EU RoHS Directive requirements. Toshiba confirms RoHS compliance for this part in its environmental documentation, and the device carries appropriate marking per JEDEC standards for lead-free packaging.
What is the typical propagation delay of TC7SET125F(TE85L,F) at 5 V?
The typical propagation delay (tPLH/tPHL) of TC7SET125F(TE85L,F) is 3.7 ns at VCC = 5.0 V and CL = 15 pF, as specified in Section 9.4 ("AC Characteristics") of the Toshiba datasheet. This value is measured under standard test conditions with 3 ns input rise/fall times.
