Product details
Overview
TL714CDR from Texas Instruments is a high-speed differential comparator fabricated in bipolar Schottky technology, featuring differential inputs, TTL-compatible output, 6 ns typical propagation delay, 10 mV typical hysteresis, and operation from a single 5-V supply. It serves as a disk-memory read-chain data comparator in high-frequency digital systems.
For engineers reviewing the TL714CDR datasheet, TL714CDR pinout, TL714CDR application, or TL714CDR equivalent, key selection criteria include propagation delay matching, input hysteresis tolerance, TTL-level output drive capability, common-mode input range (1.4 V to VCC−1.4 V), and SOIC-8 thermal performance (θJA = 97°C/W).
Technical Context
The TL714CDR implements a self-biasing differential input stage with internal hysteresis to suppress noise-induced switching. Its symmetrical TTL-compatible output delivers VOH ≥ 2.7 V at −1 mA and VOL ≤ 0.5 V at 16 mA, enabling direct interfacing with standard logic families.
Designed for single-supply 5-V operation (4.75–5.25 V), it supports common-mode input voltages from 1.4 V to VCC−1.4 V and exhibits 2.9 kΩ differential input resistance. Maximum operating frequency reaches 50 MHz under CL = 25 pF, tr/tf ≤ 4 ns conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay (tPLH/tPHL) | 6 ns typ - enables sub-10 ns decision timing in high-speed data acquisition paths |
| Hysteresis (Vhys) | 10 mV typ - provides noise immunity against <10 mV differential input fluctuations |
| Supply voltage (VCC) | 4.75–5.25 V - compatible with standard 5-V logic rails without regulation overhead |
| Output drive (IOL/IOH) | 16 mA / −1 mA - directly drives multiple TTL inputs without external buffering |
| Input common-mode range | 1.4 V to VCC−1.4 V - supports rail-to-rail signal detection within 1.4 V of supply rails |
| Max operating frequency | 50 MHz - suitable for disk read-channel clock/data recovery up to 50 Mbps |
| Thermal impedance (θJA) | 97°C/W - defines power derating limit in SOIC-8 PCB layouts with standard copper area |
Pinout & Package
TL714CDR is housed in an 8-pin SOIC (D) package per JEDEC MS-012 variation AA, 1.75 mm max height, with 1.27 mm lead pitch and Q1 pin-1 quadrant orientation on tape-and-reel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused pad - must remain unconnected; no routing or grounding required |
| 2 (IN−) | Inverting input | Differential input node referenced to IN+; accepts signals within 1.4 V to VCC−1.4 V common-mode range |
| 3 (IN+) | Non-inverting input | Primary differential input; threshold crossing triggers TTL output state change |
| 4 (NC) | No internal connection | Unused pad - electrically isolated; no PCB trace or via needed |
| 5 (VCC) | Positive supply | Single 5-V rail input; bypass capacitor (0.1 µF) recommended adjacent to pin |
| 6 (NC) | No internal connection | Unused pad - no internal bond wire; leave floating or omit from layout |
| 7 (OUT) | TTL-compatible output | Active-high logic output; sinks 16 mA, sources −1 mA; interfaces directly with 74LS/74F families |
| 8 (GND) | Ground reference | Return path for supply and output current; requires low-impedance connection to system ground plane |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed differential comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM360M | Higher supply current (15 mA vs. 12 mA typ), 25 ns propagation delay, no built-in hysteresis | Requires external hysteresis network; less suitable for noisy disk-read environments | Prefer TL714CDR where integrated hysteresis and sub-10 ns delay are critical |
| MAX961ESA+ | CMOS process, 4.5 ns propagation delay, rail-to-rail inputs, 3.3 V/5 V dual-supply support | Better for mixed-voltage systems but lacks native TTL output drive strength | Choose TL714CDR when direct TTL fanout and 5-V-only operation are required |

FAQ
What is the maximum operating frequency supported by the TL714CDR?
The TL714CDR supports a maximum operating frequency of 50 MHz under specified test conditions: VID = ±250 mV, CL = 25 pF, tr/tf = 4 ns, and 50% input duty cycle. This rating reflects its capability in high-speed disk read-channel and data acquisition applications where precise timing alignment is essential. The TL714CDR achieves this performance while maintaining TTL-compatible output drive and 6 ns propagation delay.
Does the TL714CDR require external hysteresis components?
No, the TL714CDR integrates 10 mV typical hysteresis internally, eliminating the need for external feedback resistors. This self-contained hysteresis improves noise immunity in disk memory read chains and other high-speed differential sensing applications. The TL714CDR's hysteresis is fixed and not user-adjustable, ensuring consistent performance across temperature and supply variations without design overhead.
What is the common-mode input voltage range for the TL714CDR?
The TL714CDR supports a common-mode input voltage range of 1.4 V to VCC−1.4 V at 5 V supply, i.e., 1.4 V to 3.6 V. This range allows reliable operation with signals centered near mid-supply or biased close to rails, making the TL714CDR suitable for interfacing with various analog front-ends without external level shifting. The specification is guaranteed over the full 0°C to 70°C operating temperature range.
Can the TL714CDR drive standard TTL logic loads directly?
Yes, the TL714CDR features a TTL-compatible output stage capable of sourcing −1 mA and sinking 16 mA, enabling direct connection to multiple 74LS or 74F logic inputs without external pull-up resistors or buffers. Its VOH ≥ 2.7 V and VOL ≤ 0.5 V meet standard TTL voltage thresholds, ensuring robust logic-level translation. This capability is intrinsic to the TL714CDR's bipolar Schottky design and is verified across temperature and supply variations.
What package type and reel specifications apply to the TL714CDR?
The TL714CDR is supplied in an 8-pin SOIC (D) package with tape-and-reel packaging: 2500 units per reel, reel diameter 330 mm, reel width 12.4 mm, and Q1 pin-1 quadrant orientation. The package complies with JEDEC MS-012 variation AA, has 1.27 mm lead pitch, and 1.75 mm max height. These mechanical and packaging details are standardized for automated SMT placement and are documented in TI's D0008A outline drawing for the TL714CDR.
