Product details

Active production — BOM-fit decision

The TLC3704IN: It is a quad voltage comparator built on the LinCMOS™ series, delivering CMOS, push-pull, and TTL-compatible output drive up to 20 mA per channel.

Supply range and propagation delay — threshold-crossing speed

Maximum propagation delay is 4.5 µs, which sets the upper bound on how fast the output transitions after the input crosses the threshold — for a 100 kHz signal the comparator still settles within half a period, but above 200 kHz the delay eats into the timing margin.

Input bias and quiescent current — low-power signal integrity

Input bias current is 5 pA maximum at 5 V — this is negligible for a 10 kΩ source impedance, but for a 1 MΩ high-impedance sensor the bias-induced offset voltage (5 pA × 1 MΩ = 5 µV) is well below the 5 mV maximum input offset, so the error stays within the datasheet window.

Housed in a 14-pin DIP (0.300-inch body width) with through-hole mounting — the supplier device package is 14-PDIP, which mates with standard 0.100-inch pitch sockets or solder-in board holes without reflow profiling.

Frequently asked questions

When sourcing TLC3704IN, what is the closest functional alternative — LP311DR?

The LP311DR is a single differential comparator with open-collector/open-emitter output in a surface-mount package, while the TLC3704IN is a quad general-purpose comparator with CMOS/push-pull/TTL output in a through-hole DIP-14 — they are not pin-compatible and serve different board layouts and output drive requirements. The TLC3704IN does not drop into a panel wired for the LP311DR without a board revision.
