Product details
Overview
LT1714IGN#TRPBF from Analog Devices (formerly Linear Technology) is a dual, ultrafast rail-to-rail comparator with complementary TTL/CMOS-compatible outputs and independent latch enable inputs per channel. It delivers 7ns propagation delay at 20mV overdrive, operates from 2.4V to 12V single supply or ±2.4V to ±6V dual supplies, and features input common-mode range extending 100mV beyond both rails - enabling use in high-speed crystal oscillator circuits, current-sense monitoring for switching regulators, and fast pulse discriminators.
For engineers reviewing the LT1714IGN#TRPBF datasheet, LT1714IGN#TRPBF pinout, LT1714IGN#TRPBF application, or LT1714IGN#TRPBF equivalent, this page provides verified technical context, exact pin functions for GN16 SSOP layout, latch timing parameters (tLPD = 8ns, tSU = 1.5ns), rail-to-rail input/output behavior under ±5V and 5V operation, and validated alternatives for high-speed comparator selection in ATE, sampling, and window-detection systems.
Technical Context
The LT1714IGN#TRPBF integrates two independent comparators sharing no internal signal paths, each with rail-to-rail differential input stage (NPN/PNP pair), matched complementary outputs capable of sinking 10mA to within 0.5V of GND and sourcing 10mA to within 0.7V of V+, and dedicated latch enable pins with 100mV hysteresis. Its input stage avoids phase reversal when inputs exceed supply rails by up to 100mV, and supports common-mode voltages from –5.1V to +5.1V on ±5V supplies.
Propagation delay is specified at 7–10ns (typ) for 20mV overdrive and 8.5ns for 5mV overdrive, with differential delay ≤3ns; output timing jitter is 15psRMS at 30MHz. The device uses internal TTL/CMOS-compatible latches that hold output state while latch enable is high, with latch propagation delay of 8ns and zero hold time requirement.
Key Specifications

Pinout & Package
LT1714IGN#TRPBF is housed in a 16-lead narrow SSOP (GN) package, 0.150" body width, with exposed pad not connected internally. Pin spacing is 0.025" (0.635mm), overall dimensions 0.229" × 0.150". Thermal resistance θJA = 120°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | –IN A | Inverting input of Channel A comparator - accepts rail-to-rail signals; biased via external network in oscillator applications. |
| 2 | +IN A | Noninverting input of Channel A - used with –IN A for differential sensing or single-ended threshold comparison. |
| 3, 6 | V– | Negative supply pin (dual-pin connection required) - must be tied together externally; supports –7V to 0V range. |
| 4, 5 | V+ | Positive supply pin (dual-pin connection required) - must be tied together externally; supports 2.4V to 7V range. |
| 7 | +IN B | Noninverting input of Channel B - electrically isolated from Channel A; enables independent dual-threshold detection. |
| 8 | –IN B | Inverting input of Channel B - paired with +IN B for second independent comparison path. |
| 9 | LATCH ENABLE B | Active-high latch control for Channel B outputs - internal hysteresis prevents false triggering from noise or slow edges. |
| 10 | GND | Ground reference for Channel B - separate from Channel A ground (Pin 15); recommended to tie both to system ground plane. |
| 11, 12 | QB, Q̅B | Complementary noninverting/inverting outputs of Channel B - rail-to-rail swing, TTL/CMOS compatible, drive capability ±10mA. |
| 13, 14 | Q̅A, QA | Complementary inverting/noninverting outputs of Channel A - identical drive specs to Channel B; pin order inverted vs standard convention. |
| 15 | GND | Ground reference for Channel A - not internally connected to Pin 10; requires external grounding for optimal noise immunity. |
| 16 | LATCH ENABLE A | Active-high latch control for Channel A outputs - fully independent timing control; supports asynchronous dual-channel latching. |

FAQ
What is the maximum operating supply voltage for LT1714IGN#TRPBF?
The LT1714IGN#TRPBF supports a maximum total supply voltage of 12.6V across V+ and V– pins. When operated on single supply, V+ to GND may be up to 12.6V; for dual supply, V+ to V– must not exceed 12V, and V– must remain between –7V and 0V. Exceeding these limits risks permanent damage per Absolute Maximum Ratings.
Does LT1714IGN#TRPBF require external pull-up resistors on its outputs?
No, the LT1714IGN#TRPBF does not require external pull-up resistors. Its rail-to-rail complementary outputs actively source up to 10mA and sink up to 10mA, delivering VOH ≥ V+ – 0.7V and VOL ≤ 0.5V under load - fully compatible with TTL and CMOS logic families without external biasing.
How does the latch function behave when the latch enable pin is left floating?
When the latch enable pin is left floating on LT1714IGN#TRPBF, it will float to a low state due to internal design, resulting in transparent (non-latched) operation. For reliable latched behavior, the pin must be driven actively high; for flow-through operation, it should be intentionally grounded rather than left open.
Can LT1714IGN#TRPBF operate with a 3V single supply?
Yes, the LT1714IGN#TRPBF is fully specified and characterized at 2.7V, 5V, and ±5V supplies. At 3V single supply (V+ = 3V, V– = 0V), it maintains 7–10ns propagation delay, rail-to-rail input range (–0.1V to 3.1V), and output swing (VOH ≥ 2.3V, VOL ≤ 0.5V at 1mA), meeting all key performance metrics.
What is the purpose of the dual GND pins (Pins 10 and 15) on LT1714IGN#TRPBF?
Pins 10 and 15 are separate ground connections for Channel B and Channel A, respectively. Though not internally connected, both must be tied to the system ground plane to minimize crosstalk and ensure matched propagation delay between channels. This separation improves channel-to-channel isolation in high-speed dual-comparator applications.
