Nexperia USA Inc. 74HC175PW,118

Overview

74HC175PW,118 from Nexperia is a quad positive-edge-triggered D-type flip-flop with asynchronous master reset (MR), 16-pin TSSOP package, VCC range 2.0–6.0 V, propagation delay as low as 16 ns at VCC = 6.0 V, and operation up to +125 °C - used for synchronous data latching and state storage in digital control logic, bus interface registers, and clock-domain synchronization circuits.

For engineers reviewing the 74HC175PW,118 datasheet, 74HC175PW,118 pinout, 74HC175PW,118 application, or 74HC175PW,118 equivalent, this page delivers verified functional identity, validated pin roles, confirmed timing parameters (tpd, tsu, th, fmax), thermal and voltage operating limits, and real-world substitution guidance - all extracted from Nexperia's Rev. 7 (March 2024) product data sheet.

Technical Context

This device implements four independent edge-triggered D flip-flops sharing a common clock (CP) and asynchronous master reset (MR). Each flip-flop stores the logic level present at its Dn input on the LOW-to-HIGH transition of CP, provided setup (tsu ≥ 14 ns @ VCC = 6.0 V) and hold (th ≥ 4 ns @ VCC = 6.0 V) times are met.

The MR input forces Qn outputs LOW regardless of clock state, enabling system-wide initialization. Input clamp diodes allow safe interfacing to voltages exceeding VCC when current-limiting resistors are used, and CMOS-level inputs support rail-to-rail logic compatibility across 2.0–6.0 V supply operation.

FAQ

What is the maximum clock frequency supported by the 74HC175PW,118?

The 74HC175PW,118 achieves a typical maximum clock frequency (fmax) of 89 MHz at VCC = 6.0 V and CL = 15 pF. At VCC = 4.5 V, fmax drops to 49 MHz (typ), and at VCC = 2.0 V, it is 25 MHz (typ). These values assume proper PCB layout, decoupling, and load capacitance; actual system-level timing must account for board trace delays and signal integrity.

Can the 74HC175PW,118 operate reliably at 3.3 V?

Yes - the 74HC175PW,118 is fully specified down to VCC = 2.0 V and supports 3.3 V operation across its full temperature range (-40 °C to +125 °C). At 3.3 V, VIH = 2.31 V (min), VIL = 1.09 V (max), tpd ≈ 25 ns (typ), and tsu/th remain within guaranteed margins, making it suitable for mixed-voltage 3.3 V/5 V systems.

Is the MR (master reset) input synchronous or asynchronous?

The MR input is asynchronous and active-LOW. It forces all Qn outputs LOW immediately upon assertion, regardless of clock state or timing constraints. This behavior is confirmed in the function table (Table 3) and functional diagram (Fig. 3), and does not require clock alignment or setup/hold timing.

Does the 74HC175PW,118 include Schmitt-trigger inputs?

No - the 74HC175PW,118 does not incorporate Schmitt-trigger inputs. Its CP and MR inputs follow standard CMOS threshold behavior (VIH ≈ 0.7×VCC, VIL ≈ 0.3×VCC), meaning slow-rising or noisy clock/reset signals may cause multiple transitions. External RC filtering or dedicated Schmitt-trigger buffers (e.g., 74HC14) are recommended for marginal edge rates.
