2.3.2 TLV3501 and TLV3601/3 High-Speed Comparators

The TLV360x and TLV350x families of push-pull output comparators features a fast 2.5 ns and 4.5 ns propagation delay respectively and operation from 2.4 to 5.5 V. Rail-to-rail input common-mode ranges make these comparators a well-suited for low-voltage applications. The single-ended, push-pull outputs directly drive either CMOS or transistor-transistor logic (TTL) logic. Likewise, the TLV3603 has an adjustable hysteresis feature that can be configured to reject noise in the system.

Microsize packages provide options for portable and space-restricted applications.

Figure 2-5 shows a block diagram of the TLV3501 and TLV3601.
