onsemi MC74VHC1G08MU2TCG

Overview

MC74VHC1G08MU2TCG from onsemi is a single 2-input CMOS AND gate in a 1.2 mm × 1.0 mm UDFN6 package with CMOS-level input thresholds, 3.5 ns propagation delay at 5 V, ±8 mA drive capability at 3.0 V, and over-voltage tolerant inputs/outputs up to 5.5 V - used for level-shifting and logic interfacing between 3 V and 5 V subsystems in portable power management circuits.

For engineers reviewing the MC74VHC1G08MU2TCG datasheet, pinout, applications, or equivalent options, key selection considerations include its 2.0–5.5 V supply range, IOFF partial power-down protection, 5.5 V overvoltage tolerance on all I/O pins regardless of VCC, and compatibility with SC-88A, SC-74A, SOT-953, and multiple UDFN6 footprint variants.

Technical Context

The MC74VHC1G08MU2TCG implements standard positive-logic AND functionality (Y = A · B) with rail-to-rail output swing and guaranteed switching across −55°C to +125°C. Its input structure includes diode clamps enabling 5.5 V tolerance independent of VCC, supporting mixed-voltage domain interfacing without external components.

It features IOFF circuitry that disables I/O leakage when VCC = 0 V, preventing back-powering of powered-down rails. Output drive strength is specified at ±8 mA at 3.0 V, with propagation delays tightly characterized from 3.0 V to 5.5 V under 15 pF and 50 pF loads.

FAQ

What is the logic function and truth table of the MC74VHC1G08MU2TCG?

The MC74VHC1G08MU2TCG implements a single 2-input AND gate with Y = A · B. Its truth table is: A=L/B=L → Y=L; A=H/B=L → Y=L; A=L/B=H → Y=L; A=H/B=H → Y=H. Inputs follow CMOS thresholds (VIH ≥ 70% VCC, VIL ≤ 30% VCC), and outputs swing rail-to-rail. This behavior is verified across −55°C to +125°C and 2.0–5.5 V supply range per the official onsemi datasheet Rev. 33.

Does the MC74VHC1G08MU2TCG support level shifting between 3 V and 5 V systems?

Yes, the MC74VHC1G08MU2TCG supports bidirectional level shifting: its inputs and outputs tolerate up to 5.5 V regardless of VCC, allowing 5 V signals to be safely applied when VCC = 3.3 V, and vice versa. This eliminates external resistors or translators in mixed-voltage designs. The MC74VHC1G08MU2TCG achieves this via integrated input clamps and overvoltage-safe output structures, as confirmed in the Absolute Maximum Ratings and DC Characteristics sections of the datasheet.

What is the pin configuration and marking for MC74VHC1G08MU2TCG?

The MC74VHC1G08MU2TCG uses a 6-pin UDFN package (Case 517AA, 1.2 mm × 1.0 mm, 0.4 mm pitch) with pin 1 identified by a dot or beveled corner. Pinout is: 1=B, 2=A, 3=GND, 4=Y, 5=NC, 6=VCC. Marking consists of a 2-character device code followed by date code (e.g., "V2M"), per the Generic Marking Diagram in the datasheet. Pin 1 orientation is "2" as specified in the Ordering Information table.

Is the MC74VHC1G08MU2TCG suitable for automotive applications?

Yes - the MC74VHC1G08MU2TCG is AEC-Q100 qualified (Grade 1: −40°C to +125°C junction) and PPAP capable when ordered with the "−Q" suffix (e.g., MC74VHC1G08MU2TCG-Q). While the base part number MC74VHC1G08MU2TCG shares identical electrical and thermal specs, automotive qualification requires the −Q variant. The datasheet explicitly lists "−Q Suffix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements".

What is the maximum operating frequency supported by the MC74VHC1G08MU2TCG?

The MC74VHC1G08MU2TCG does not specify a maximum clock frequency, but its propagation delay (tPD) is 3.5 ns (typ) at 5 V with 15 pF load - implying reliable operation up to ~100 MHz for toggle-rate-limited applications. AC characteristics are validated under defined test conditions (CL = 15/50 pF, VCC = 3.0–5.5 V), and timing margins must be verified per actual layout and load. The MC74VHC1G08MU2TCG is intended for general-purpose combinational logic, not synchronous clock distribution.
