Product details
Overview
74LVT00D,112 from NXP Semiconductors (formerly Philips) is a 3.3 V quad 2-input NAND gate logic IC in 14-pin SO package. It delivers 2.7 ns typical propagation delay (tPLH/tPHL), 3 pF input capacitance, and supports –40°C to +85°C operation. It serves as a high-speed combinational logic element in bus interface and control signal conditioning circuits.
For engineers reviewing the 74LVT00D,112 datasheet, 74LVT00D,112 pinout, 74LVT00D,112 application, or 74LVT00D,112 equivalent, key selection criteria include its LVT logic family compatibility, 3.3 V supply tolerance, output drive capability (–20 mA/32 mA), and SO14 footprint for space-constrained digital control boards.
Technical Context
The 74LVT00D,112 implements four independent 2-input NAND gates using advanced BiCMOS LVT (Low-Voltage TTL) technology, enabling interoperability between 3.3 V and 5 V systems via TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V). Its outputs are fully buffered and capable of driving standard LVTTL loads.
It operates within a 2.7 V to 3.6 V supply range and features rail-to-rail input voltage tolerance (0–5.5 V), with absolute maximum ratings up to +4.6 V on VCC and +7.0 V on inputs/outputs. The device meets JEDEC JESD8-5 and JESD8-B standards for 3.3 V logic interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC00APWR | Lower VCC range (1.65–3.6 V); 3.5 ns max tPD at 3.3 V; 24 mA IOL | Higher noise immunity at 1.8 V operation; less drive strength than 74LVT00D,112 | Prefer for dual-supply (1.8/3.3 V) systems requiring lower static current |
| 74ALVC00D,112 | Same SO14 package; 2.5 ns max tPD; 24 mA IOL; 1.65–3.6 V VCC | Improved speed vs. LVT but reduced output drive; not 5 V-tolerant inputs | Choose when 5 V input tolerance is unnecessary and sub-3 ns delay is prioritized |
Compared with SN74LVC00APWR and 74ALVC00D,112, the 74LVT00D,112 offers superior 5 V-tolerant inputs and higher sink current (32 mA), making it optimal for legacy interface bridging and moderate-power digital gating where robustness outweighs ultra-low voltage operation.

FAQ
What logic family does the 74LVT00D,112 belong to, and how does it differ from standard TTL?
The 74LVT00D,112 belongs to the Low-Voltage TTL (LVT) logic family. Unlike standard TTL, it operates natively at 3.3 V while retaining TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V), enabling direct interfacing with both 3.3 V and 5 V systems. Its BiCMOS process delivers faster switching and lower power than bipolar TTL, with 2.7 ns typical propagation delay and 3 pF input capacitance - characteristics confirmed in the Philips 1996 Product Specification.
Does the 74LVT00D,112 support 5 V inputs while powered from 3.3 V?
Yes, the 74LVT00D,112 supports input voltages up to 5.5 V while operating from a 3.3 V supply, as specified in the "Recommended Operating Conditions" table (VI = 0 to 5.5 V). This 5 V-tolerant input capability is a defining feature of the LVT family and eliminates the need for external level shifters when interfacing with legacy 5 V logic - a key advantage over LVC or ALVC variants.
What is the maximum output sink current for the 74LVT00D,112, and under what conditions is it rated?
The 74LVT00D,112 is rated for 32 mA maximum output sink current (IOL) at VCC = 3.0 V and Tamb = –40°C to +85°C, per the "Recommended Operating Conditions" table. This rating applies when the output is driven low and ensures reliable operation into moderate loads such as LEDs or multiple LVTTL inputs without thermal derating in industrial temperature ranges.
Which package type corresponds to the 74LVT00D,112 ordering code?
The suffix "D" in 74LVT00D,112 denotes the 14-pin plastic small outline (SO) package per SOT108-1, with 3.9 mm body width and 1.27 mm lead pitch. This is explicitly stated in the "Ordering Information" section of the Philips datasheet, distinguishing it from DB (SSOP) and PW (TSSOP) variants.
Can the 74LVT00D,112 be used in place of the 74LS00 in existing designs?
The 74LVT00D,112 is not a direct drop-in replacement for the 74LS00 due to differences in supply voltage (3.3 V vs. 5 V), output drive polarity (active-low vs. open-collector compatible), and speed profile. While pinout is identical, substituting it requires verifying VCC compatibility, load conditions, and input threshold alignment - the 74LVT00D,112's 0.8 V VIL and 2.0 V VIH differ from LS TTL's 0.8 V/2.0 V but operate only at 3.3 V, not 5 V.
