Diodes Incorporated PI74FCT162374ATV

Overview

PI74FCT162374ATV from Pericom Semiconductor is a 16-bit, 3-state octal register IC with dual 8-bit register configuration, ±24 mA balanced output drivers, 5 V supply operation, and integrated current-limiting resistors for controlled edge rates-used in high-speed backplane and bus interface applications requiring low ground bounce.

For engineers reviewing the PI74FCT162374ATV datasheet, PI74FCT162374ATV pinout, PI74FCT162374ATV application, or PI74FCT162374ATV equivalent, key selection criteria include output drive symmetry, VOLP < 0.6 V at 5 V/25°C, TSSOP-48 package compatibility, and support for live insertion via controlled slew rate without external termination.

Technical Context

This device implements two independent 8-bit D-type flip-flop banks sharing buffered clock and output-enable controls, enabling flexible 8-bit or unified 16-bit register operation. Its CMOS-based FCT logic delivers TTL-compatible input thresholds with hysteresis and operates across –40°C to +85°C.

The PI74FCT162374ATV uses on-die current-limiting resistors at all outputs to reduce switching noise and suppress ground bounce (typical VOLP < 0.6 V), eliminating need for external series termination in most parallel bus interfaces-critical for stable signal integrity in dense PCB layouts.

FAQ

Is PI74FCT162374ATV pin-compatible with other members of the PI74FCT16x374 family?

Yes-PI74FCT162374ATV shares identical pinout and package (48-pin TSSOP) with PI74FCT16374ATV and PI74FCT162H374ATV. Functional differences lie in output drive strength (±24 mA vs. –32/+64 mA), bus-hold presence, and ground bounce performance-not physical layout.

Does PI74FCT162374ATV require external pull-up or pull-down resistors on inputs?

No-inputs lack bus-hold circuitry (unlike PI74FCT162H374ATV), but hysteresis (100 mV) and TTL-compatible thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) provide sufficient noise margin. External biasing is only needed if inputs float unconnected in system design.

What is the maximum clock frequency supported by PI74FCT162374ATV?

While not explicitly specified as a maximum frequency, the 10 ns max t_PLH/t_PHL and 3 ns min t_W (clock pulse width) support reliable operation up to ~100 MHz in typical 50 pF load conditions. System-level timing must account for setup/hold (t_SU = 2.0 ns, t_H = 1.5 ns).

Can PI74FCT162374ATV be used in mixed-voltage systems with 3.3 V logic?

It is a 5 V-only device (V_CC = 5 V ±10%). Inputs tolerate 3.3 V logic HIGH levels (VIH min = 2.0 V), but outputs swing rail-to-rail at 5 V-direct connection to 3.3 V CMOS inputs risks overvoltage damage unless interfaced via level translators or series resistors with clamping diodes.
