Product details
Overview
74LVT16244BEV,157 from Nexperia is a 3.3 V, 16-bit non-inverting 3-state buffer and line driver in VFBGA56 package, delivering ±64 mA/−32 mA drive capability, TTL-compatible I/O, and bus-hold inputs for 5 V interface systems. It supports four independent 4-bit buffers or unified 16-bit data routing in industrial control backplanes and high-density FPGA I/O expansion.
For engineers reviewing the 74LVT16244BEV,157 datasheet, 74LVT16244BEV,157 pinout, 74LVT16244BEV,157 application, or 74LVT16244BEV,157 equivalent, this page delivers verified electrical specs, ball mapping for VFBGA56, bus-hold behavior, propagation delays down to 0.5 ns, and direct alternatives for 3.3 V logic interfacing with legacy 5 V buses.
Technical Context
This BiCMOS device operates at 2.7–3.6 V supply and features active-low 3-state enable per 4-bit group (1OE–4OE), enabling selective bus isolation. Its bus-hold circuitry eliminates external pull-ups on unused inputs, maintaining valid logic states without additional components.
Dynamic performance includes tPLH/tPHL ≤ 3.2 ns at 3.0–3.6 V, tPZH/tPHZ ≤ 4.5 ns, and low input/output capacitance (CI = 3 pF, CO = 9 pF), supporting high-speed signal integrity in compact PCB layouts where VFBGA56's 4.5 × 7 mm footprint minimizes board area.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Key Features
| Feature | Design Value |
|---|---|
| 16-bit 3-state buffering | Enables bidirectional or multiplexed bus architectures by selectively isolating data lanes without contention. |
| TTL-compatible I/O | Accepts 5 V inputs while operating at 3.3 V supply - eliminates level translators in mixed-voltage system upgrades. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16244ADGGR | Lower drive (±24 mA), LVC family, TSSOP48 only - no VFBGA option. | Suitable for lower-current 3.3 V-only systems; lacks 5 V input tolerance. | Select when cost sensitivity outweighs 5 V interface needs and board space permits TSSOP48. |
| 74ALVCH16244PW,118 | ALVC family, same VFBGA56 package, ±24 mA drive, 5 V tolerant inputs. | Higher speed (tPD ≤ 2.8 ns), lower ICC, but reduced output current limits. | Prefer for ultra-low-power, high-speed 16-bit buffering where 24 mA drive suffices and 5 V tolerance remains critical. |
Compared with SN74LVC16244ADGGR and 74ALVCH16244PW,118, the 74LVT16244BEV,157 uniquely combines 5 V input tolerance, ±64 mA sink capability, and VFBGA56 packaging - making it optimal for space-constrained industrial backplanes requiring robust 5 V interoperability and high-current drive.

FAQ
What is the maximum input voltage rating for 74LVT16244BEV,157?
The 74LVT16244BEV,157 supports input voltages up to 5.5 V, enabling direct connection to 5 V logic families without level-shifting circuitry. This 5 V tolerance applies across the full operating temperature range (−40 °C to +85 °C) and is specified in Table 5 of the Nexperia datasheet under VI parameter. The device uses BiCMOS input structures to safely clamp and translate these higher voltages while operating from a 3.3 V supply.
Does 74LVT16244BEV,157 include bus-hold functionality, and how does it behave?
Yes, the 74LVT16244BEV,157 integrates bus-hold circuitry on all data inputs (1A0–4A3). When an input floats, the bus-hold feature maintains its last valid logic state using ±75 µA to ±135 µA feedback current - eliminating external pull-up or pull-down resistors. This behavior is confirmed in Section 2 (Features and benefits) and Table 6 (IBHL/IBHH parameters) of the datasheet, and functions independently of VCC level within 0 V to 3.6 V.
What is the propagation delay specification for 74LVT16244BEV,157 at 3.3 V operation?
At VCC = 3.0 V to 3.6 V, the 74LVT16244BEV,157 exhibits tPLH and tPHL propagation delays of 0.5 ns (minimum) to 3.2 ns (maximum), as specified in Table 7 of the Nexperia datasheet. These values apply to signal transitions from input (A) to corresponding output (Y) under loaded conditions (CL = 50 pF, RL = 500 Ω). The low typical delay (1.7–1.8 ns) ensures timing-critical applications like memory address latching remain within budget.
How many ground and power balls does the VFBGA56 package of 74LVT16244BEV,157 provide?
The 74LVT16244BEV,157 in VFBGA56 (SOT702-1) package provides eight dedicated ground balls (B3, B4, D3, D4, G3, G4, J3, J4) and four dedicated VCC balls (C3, C4, H3, H4), as documented in Table 2 (Pin description) of the datasheet. This distributed power/ground architecture reduces impedance, minimizes ground bounce, and improves signal integrity in high-speed digital designs.
Is 74LVT16244BEV,157 suitable for hot-swap or live-insertion applications?
Yes, the 74LVT16244BEV,157 supports live insertion and extraction, as explicitly stated in Section 2 (Features and benefits) of the Nexperia datasheet. Its BiCMOS construction, latch-up protection exceeding 500 mA (JESD78B Class II), and controlled power-up 3-state behavior prevent bus contention and damage during hot-plug events - making it appropriate for modular backplane systems requiring field-replaceable units.
