Product details
Overview
M74HCT7007RM13TR from STMicroelectronics is a high-speed CMOS hex buffer (non-inverting) fabricated in silicon gate C2MOS technology, designed for TTL/NMOS interface compatibility with VIH ≥ 2.0 V, VIL ≤ 0.8 V, and symmetrical output drive of ±4 mA. It operates at 4.5–5.5 V, delivers 14 ns typical propagation delay, and supports industrial temperature range (−55 °C to +125 °C) in TSSOP-14 package.
For engineers reviewing the M74HCT7007RM13TR datasheet, M74HCT7007RM13TR pinout, M74HCT7007RM13TR application, or M74HCT7007RM13TR equivalent, this device serves as a logic-level translation and fanout buffer in mixed-voltage digital systems requiring low quiescent current (1 µA max), balanced tPLH/tPHL timing, and ESD-protected inputs.
Technical Context
The M74HCT7007RM13TR implements six independent non-inverting buffer gates with TTL-compatible input thresholds and rail-to-rail CMOS output swing. Its C2MOS process enables low ICC (≤10 µA over −40 to +85 °C) while maintaining 14 ns typical tPD at VCC = 4.5 V and CL = 50 pF.
Input protection diodes, symmetrical IOH/IOL (≥4 mA), and matched propagation delays (tPLH ≅ tPHL) ensure robust signal integrity in bus-driving and level-shifting roles across wide temperature and supply ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures stable operation across standard 5 V supply tolerances. |
| tPD (Typ.) | 14 ns at VCC = 4.5 V, CL = 50 pF - Enables high-speed data path buffering up to ~35 MHz toggle rate. |
| IOH / IOL | ≥ −4 mA / ≥ +4 mA - Supports direct driving of TTL loads or fanout to ≥10 LS-TTL inputs. |
| VIH / VIL | ≥ 2.0 V / ≤ 0.8 V - Guarantees reliable recognition of TTL logic levels without external level shifters. |
| ICC (Max) | 1 µA at TA = 25 °C - Minimizes static power in always-on control logic or standby interfaces. |
| Operating Temp | −55 °C to +125 °C - Qualified for automotive under-hood, industrial PLC, and aerospace avionics environments. |
| CIN | 10 pF - Limits capacitive loading on upstream drivers, preserving edge integrity in dense PCB layouts. |
Pinout & Package
TSSOP-14 (Thin Shrink Small Outline Package), 4.9 × 6.4 mm body, 0.65 mm pitch, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | 1A–6A Inputs | CMOS/TTL-compatible digital inputs with ESD protection; accept 0–VCC voltage range. |
| 2, 4, 6, 8, 10, 12 | 1Y–6Y Outputs | Push-pull CMOS outputs delivering full rail-swing and ±4 mA drive capability. |
| 7 | GND | Dedicated ground reference for noise immunity and stable logic threshold referencing. |
| 14 | VCC | Primary 4.5–5.5 V supply rail; decoupling required within 1 cm for AC performance. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-Compatible Input Thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V enable direct connection to legacy 5 V TTL buses without level translation. |
| Balanced Propagation Delays | tPLH ≅ tPHL ensures minimal duty cycle distortion in clock or data waveform buffering applications. |
| Symmetrical Output Drive | |IOH| = IOL ≥ 4 mA allows uniform rise/fall time control and consistent load switching behavior. |
| Low Quiescent Current | ICC ≤ 1 µA at 25 °C reduces system-level standby power in battery-backed or energy-sensitive designs. |
| ESD-Protected Inputs | All inputs include integrated protection circuits rated per IEC 61000-4-2 (±2 kV contact), improving board-level reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT07DR | Same logic function, identical DC specs, but SOIC-14 package (wider pitch, larger footprint). | Less suitable for space-constrained PCBs where TSSOP-14 density is required. | Select when board layout prioritizes hand-solderability or legacy SOIC footprint reuse. |
| 74HCT7007PW,118 | NXP variant in TSSOP-14; identical pinout and electrical specs per datasheet Rev. 9 (2020). | No functional difference; qualified for same industrial temp range and drive strength. | Valid second-source option with identical form-fit-function and supply chain diversification benefit. |
Compared with SN74HCT07DR and 74HCT7007PW,118, the M74HCT7007RM13TR offers identical electrical performance in a compact TSSOP-14 package optimized for high-density routing and thermal dissipation, making it preferable for modern miniaturized control modules.

FAQ
Is M74HCT7007RM13TR pin-compatible with standard 74LS07?
Yes - it is pin- and function-compatible with 74LS07 and other 74-series hex buffers. All six inputs (pins 1,3,5,9,11,13) and outputs (2,4,6,8,10,12) match the industry-standard 14-pin layout, and GND/VCC positions (7/14) are identical. No PCB redesign is needed for drop-in replacement.
What is the maximum capacitive load this buffer can drive reliably?
The M74HCT7007RM13TR is characterized up to CL = 50 pF in AC testing, with tPD and transition times specified under that condition. While it can drive higher capacitance, sustained operation above 50 pF may increase propagation delay and reduce edge rates; for >75 pF loads, consider adding series termination or using a driver with higher IOL.
Does this part support 3.3 V input logic levels?
No - its VIH minimum is 2.0 V at VCC = 4.5–5.5 V, meaning a 3.3 V logic high meets the threshold only marginally and lacks noise margin. For reliable 3.3 V → 5 V interfacing, use a dedicated level shifter or HCT-family part with explicit 3.3 V-tolerant inputs (e.g., 74HCT3G04).
Can M74HCT7007RM13TR operate at 3.3 V supply?
No - the recommended VCC range is strictly 4.5 V to 5.5 V. Operation below 4.5 V violates specification limits: VOH drops below TTL-compatible levels, and timing parameters become undefined. Use 74LVC07A or similar for 3.3 V-only systems.
