74AVC4T774 4-bit dual supply translating transceiver 3-state Rev. 1 25 September 2017 Product data sheet 1 General description The 74AVC4T774 is a 4-bit, dual supply transceiver that enables bidirectional level translation. It features eight 1-bit input-output ports (An and Bn), four direction control inputs (DIR1, DIR2, DIR3 and DIR4), an output enable input (OE) and dual supply pins (V and V ). Both V and V can be supplied at any voltage between CC(A) CC(B) CC(A) CC(B) 0.8 V and 3.6 V making the device suitable for translating between any of the low voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V). Pins An, OE and DIRn are referenced to V and pins Bn are referenced to V . A HIGH on DIRn allows transmission from CC(A) CC(B) An to Bn and a LOW on DIRn allows transmission from Bn to An. The output enable input (OE) can be used to disable the outputs so the buses are effectively isolated. The device is fully specified for partial power-down applications using I . The I OFF OFF circuitry disables the output, preventing any damaging backflow current through the device when it is powered down. In suspend mode when either V or V are at CC(A) CC(B) GND level, both An and Bn are in the high-impedance OFF-state. 2 Features and benefits Wide supply voltage range: V : 0.8 V to 3.6 V CC(A) V : 0.8 V to 3.6 V CC(B) Complies with JEDEC standards: JESD8-12 (0.8 V to 1.3 V) JESD8-11 (0.9 V to 1.65 V) JESD8-7 (1.2 V to 1.95 V) JESD8-5 (1.8 V to 2.7 V) JESD8-B (2.7 V to 3.6 V) ESD protection: HBM JESD22-A114E Class 3B exceeds 8000 V CDM JESD22-C101C exceeds 1500 V Maximum data rates: 380 Mbit/s ( 1.8 V to 3.3 V translation) 200 Mbit/s ( 1.1 V to 3.3 V translation) 200 Mbit/s ( 1.1 V to 2.5 V translation) 200 Mbit/s ( 1.1 V to 1.8 V translation) 150 Mbit/s ( 1.1 V to 1.5 V translation) 100 Mbit/s ( 1.1 V to 1.2 V translation) Suspend mode Latch-up performance exceeds 100 mA per JESD 78 Class II Inputs accept voltages up to 3.6 V I circuitry provides partial Power-down mode operation OFFNexperia 74AVC4T774 4-bit dual supply translating transceiver 3-state Specified from -40 C to +85 C and -40 C to +125 C 3 Ordering information Table 1.Ordering information Type number Package Temperature range Name Description Version 74AVC4T774BQ -40 C to +125 C DHVQFN16 plastic dual in-line compatible thermal SOT763-1 enhanced very thin quad flat package no leads 16 terminals body 2.5 x 3.5 x 0.85 mm 74AVC4T774GU -40 C to +125 C XQFN16 plastic, extremely thin quad flat package no leads SOT1161-1 16 terminals body 1.80 x 2.60 x 0.50 mm 4 Marking Table 2.Marking codes Type number Marking code 74AVC4T774BQ C4T774 74AVC4T774GU B77 5 Functional diagram B1 B2 B3 B4 V CC(B) V CC(A) A1 DIR1 A2 DIR2 A3 DIR3 A4 DIR4 OE 001aao069 Figure 1.
