Nexperia USA Inc. 74LVC377PW,112

Overview

74LVC377PW,112 from Nexperia is an octal positive-edge-triggered D-type flip-flop with asynchronous data enable (E) input, operating across 1.2 V to 3.6 V supply, supporting mixed-voltage interfacing (5.5 V-tolerant inputs), and rated for -40 °C to +125 °C. It delivers 8-bit synchronous data latching in digital control logic, bus interface buffering, and clock-domain synchronization in industrial microcontroller peripherals.

For engineers reviewing the 74LVC377PW,112 datasheet, 74LVC377PW,112 pinout, 74LVC377PW,112 application, or 74LVC377PW,112 equivalent, key selection criteria include its 1.2–3.6 V supply range, 5.5 V overvoltage-tolerant inputs, 9.5 ns max propagation delay at 3.6 V, ±24 mA output drive, and TSSOP20 package compatibility with high-density PCB layouts.

Technical Context

This device implements eight independent edge-triggered D flip-flops sharing a common clock (CP) and active-low data enable (E). When E is LOW, each Qn output captures the corresponding Dn input on the LOW-to-HIGH CP transition, provided setup/hold timing is met. Input stability requirements mandate E be stable one setup time before the CP edge.

Its CMOS architecture enables direct TTL-level interfacing and translation between 3.3 V and 5 V logic domains. The design supports operation up to 150 MHz at 3.6 V and guarantees output skew ≤1.5 ns across all eight outputs under same-direction switching conditions.

FAQ

What is the minimum supply voltage for guaranteed operation of the 74LVC377PW,112?

The device is fully specified down to 1.2 V supply voltage, with static and dynamic parameters-including VIH/VIL thresholds, tpd, and fmax-validated across this range per Table 5 and Table 7 of the datasheet. Operation below 1.2 V is not characterized and may result in undefined timing or logic behavior.

Can the 74LVC377PW,112 safely interface with 5 V logic without external level shifters?

Yes-the inputs are overvoltage tolerant up to 5.5 V regardless of VCC, allowing direct connection to 5 V outputs. However, outputs swing only from GND to VCC (max 3.6 V), so driving 5 V inputs requires external pull-up or translation; the device does not provide bidirectional level shifting.

How is the data enable (E) input timed relative to the clock (CP) edge?

E must be stable for at least the setup time (tsu = 2.0 ns min at VCC = 3.6 V) before the LOW-to-HIGH CP transition. If E changes within this window, output behavior is undefined. Hold time (th = 0 ns min at VCC = 3.6 V) requires E to remain stable for ≥0 ns after the CP edge.

Is the 74LVC377PW,112 qualified for automotive applications?

No-it is not AEC-Q100 qualified. While rated for -40 °C to +125 °C ambient, Nexperia explicitly states in Section 14 that non-automotive-qualified products like this are unsuitable for safety-critical automotive use; it may be used in non-safety body electronics only with full customer responsibility for validation and risk mitigation.
