Product details
Overview
54FCT162245ATEB from Renesas Electronics (formerly IDT) is a military-grade 16-bit bidirectional transceiver in CERPACK package, operating from –55°C to +125°C at 5.0V ±10%. It features ±16mA balanced output drive, <250ps output skew, and dual 8-bit or unified 16-bit operation for synchronous bus interfacing in avionics and ruggedized control systems.
For engineers reviewing the 54FCT162245ATEB datasheet, 54FCT162245ATEB pinout, 54FCT162245ATEB application, or 54FCT162245ATEB equivalent, key selection criteria include military temperature compliance, controlled ground bounce (<0.6V), hysteresis-enhanced noise margin, and compatibility with legacy FCT16245T/ABT16245 interfaces.
Technical Context
The 54FCT162245ATEB implements two independent direction-controlled 8-bit transceivers via dedicated xDIR/xOE pins per side, enabling flexible A↔B data routing. Its dual-metal CMOS process delivers TTL-compatible input thresholds (VIH = 2.0V min, VIL = 0.8V max) and rail-to-rail output swing under ±16mA load.
Output drivers integrate current-limiting resistors to suppress ground bounce and undershoot, eliminating need for external series termination. The device supports asynchronous enable/disable with tPZL/tPHZ ≤ 10ns (military) and maintains high-impedance isolation (IOZH/IOZL ≤ ±1µA) when disabled.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 54FCT16245ATEB | Single 16-bit transceiver (no dual 8-bit mode); identical timing, drive, and temp range | Lacks independent DIR/OE per 8-bit bank - less flexible for partial-bus control | Select when full 16-bit synchronization is required and dual-control logic is unnecessary |
| SNJ54ABT16245J | Same pinout and function but uses older ABT process; higher ICC, no hysteresis, no ground bounce spec | Higher power consumption and reduced noise margin limit use in high-density or noisy environments | Select only for legacy ABT-only designs where FCT-level performance is not required |
Compared with 54FCT162245ATEB, the 54FCT16245ATEB offers simpler control at the cost of configurability, while SNJ54ABT16245J provides backward compatibility with higher power and lower noise immunity - making the 54FCT162245ATEB optimal for new ruggedized designs requiring flexibility and signal integrity.

FAQ
What is the maximum clock frequency supported by the 54FCT162245ATEB?
The 54FCT162245ATEB does not contain internal clocks or registers; it is an asynchronous transceiver. Its usable data rate depends on system-level timing margins. With typical propagation delay ≤7.5ns and output skew <250ps, it reliably supports bus handshaking up to 100+ MHz in well-designed 50Ω-terminated systems using proper layout practices.
Does the 54FCT162245ATEB require external pull-up or pull-down resistors on control pins?
No. The 54FCT162245ATEB has TTL-compatible input thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V) and internal hysteresis, allowing direct connection to 5V logic outputs without external biasing. Pull-up/pull-down resistors are unnecessary unless specific system-level noise or power-down states demand them.
Can the 54FCT162245ATEB operate at 3.3V supply voltage?
No. The 54FCT162245ATEB is specified only for 5.0V ±10% operation (4.5V to 5.5V). Operation outside this range violates absolute maximum ratings and may cause functional failure or reliability degradation. For 3.3V systems, consider Renesas' 74FCT162245CT or newer LVCMOS alternatives.
How many ground pins does the 54FCT162245ATEB CERPACK package have?
The 54FCT162245ATEB in CERPACK package has nine dedicated ground pins (Pins 3, 10, 19, 23, 30, 33, 36, 43, and 46), strategically distributed to minimize ground inductance and suppress simultaneous switching noise across all 16 drivers.
Is the 54FCT162245ATEB RoHS compliant?
Yes. The 54FCT162245ATEB is manufactured as a green (lead-free) part per Renesas' ordering code "PVG" designation, meeting RoHS Directive 2011/65/EU requirements. Full compliance documentation, including substance declarations and test reports, is available upon request from Aetrix Electronics.
